The Barlow Gap quadrangle was mapped by Wayne Sutherland and assisted by W. Dan Hausel in 1999. The Rattlesnake Hills district was mapped by W. Dan Hausel of the Metals and Precious Stones Section of the Wyoming State Geological Survey (WSGS) in 1995 ( Geological Map of the Rattlesnake Hills ). The results of the Rattlesnake Hills appeared in WSGS Report of Investigations 52. These mapping projects are part of an ongoing Precambrian geology and economic geology research project by the WSGS. Mapping of the Barlow Gap Quadrangle was partially funded by the US Geological Survey STATEMAP program. The Rattlesnake Hills project was funded entirely by the WSGS budget. This region of the northern Granite Mountains contains one of the best gold prospects in the State for open-pitable gold mineralization. Barlow Gap lies within the ancient Archean craton known as the Wyoming Province, and includes geologic units ranging in age from

64. The Geology Of Coarse Gold Formation The geology of Coarse gold Formation. By Chris Ralph. The goal ofmetal detecting for gold is finding coarse nuggets. In order to http://www.nuggetshooter.com/articles/CRGeologyofcoarsegoldformation.html

The Geology of Coarse Gold Formation By Chris Ralph The prospector using a metal detector is primarily interested in coarser gold as larger nuggets are easier to detect, and of course, more valuable! It turns out that coarse gold most commonly forms in small veins (for the sake of argument, lets say for our discussion that coarse gold is stuff a Penney weight or larger). Big veins, with a width and length large enough to be mined commercially underground, almost always produce small gold - wires, small pieces, etc - even though they may be fairly rich. Of course, there are a number of exceptions to this rule, but generally speaking, it is true. So why, in general,does big gold form in small veins, while mostly only small gold forms in big veins? Often, the source of the heat is some sort of cooling magma (lava, still molten or solidified but still hot). This kind of heat source throws off so much heat energy that the rock may well be warm to within 100 feet of the surface, even if the source is over 2000 feet down. The temperature does not drop off suddenly once the solution gets a short distance from the source. The drop in temperature as you move away from the heat source is gradual, and usually fairly linear, at least within a few hundred feet of the surface. So the temperature of the rock (and the water solutions as well) becomes directly related to how far they are from the heat source. The rate of cooling then becomes a simple function of how fast the fluids move upward.

E. Waite 4. BRIEF GEOLOGY The ore bodies of the Zeehan and Dundas areas are quite similar. Why then, does crocoite occur in so much abundance at Dundas and not nearby Zeehan? To find the answer, we must first of all travel back in time more than 500 million years, to the period known as the Cambrian. This period of time, named for the Roman name for Wales (Cambria), was, at the time, the oldest system of rocks in which fossils could be used for dating and correlation. The period commenced around 600 million years ago with a duration of about 100 million years. During the Cambrian period in Tasmania, sedimentary rocks, derived from the erosion of earlier formed Pre-Cambrian rocks, were deposited over a long period of time. Many of these rocks were formed in marine environments, a fact indicated by the traces of marine fossils such as trilobites, brachiopods, sponges, and other organisms. Igneous rocks (that is, rocks that have melted, and then solidified by cooling) also formed during the Cambrian. Some of these rocks, such as serpentines, and the Mount Read volcanics, are important hosts for economic minerals. The serpentines are also known as ultrabasic rocks (rocks that are comprised predominantly of ferromagnesian minerals), and may contain chromite, nickel sulphides, or "osmiridium" and other platinum group minerals. These serpentines outcrop in a number of areas in Tasmania, including Dundas, Heazlewood, Adamsfield, Ulverstone, and Beaconsfield. Only in the first two areas however, does the chromium in the serpentine combine with the other necessary ingredient, lead, that has allowed that spectacular mineral crocoite to form.

Email John Mason HERE This tale takes us back into the Lower Palaeozoic era, when North Wales was under the sea, on the margin of the ancient ocean that geologists call Iapetus (fig. 1). Scotland and Northern Ireland sat on the ocean's opposite shore. The shales that make up the Gold-belt were originally silts and muds, deposited on the old sea-bed. Fig. 1: Sketched reconstruction of Iapetus Ocean at the time of the formation of the Dolgellau Gold-belt, with present-day landmasses shown in grey. Most of these, apart from E Scandanavia and NW Canada, were in fact submerged beneath shallow seas at the time - the marginal seas of Iapetus. When the ocean closed, the ensuing continenatal collision joined together the two halves of Britain and added E New England, Nova Scotia and E Newfoundland to the American continent. The Atlantic started to open hundreds of millions of years later.

Stratigraphy of the belt is mainly defined by age-different metamorphosed volcano-plutonic associations (VPA) of the komatiite-tholeiite formation (from the base): lower tholeiite-gabbro-diabase (KT-1), lower komatiite-dunite-harzburgite (KT-2), upper tholeiite-gabbro-diabase (KT-3) and upper komatiite-dunite-harzburgite (KT-4). As well, ore-hosting litho-facial complex also includes schist-BIF-tholeiite formation which is spatially linked to the above VPA of komatiite-tholeiite formation replacing them laterally. The section is capped by rhyodacite-plagiogranite VPA which is extremely important in the Ukrainian Shield greenstone belts structure and their ore-forming processes development. It is suggested the gold mineralization is genetically linked to the fluid systems of this VPA which have been separated from the parent VPA within 3.15-3.3 Ga.

History N.L. Baroid Corporation began gold exploration on the Rossi property in 1982 and by 1985 had identified several areas of shallow low- grade gold mineralization . In 1986, Meridian Gold (then FMC Gold) entered into a 50/50 joint-venture agreement with N.L. Baroid to conduct further gold exploration on the property. Shallow exploration continued through 1989. High- grade gold mineralization was discovered in 1990 as the result of a deep exploration program. Two of 12 deep holes encountered gold grades greater than 6.8 g/t: 6.1 meters of 10.5 g/t at 479 meters; and 9.1 meters of 9.7 g/t at 404 meters. By the end of 1992, 14 of 30 deep holes drilled contained intercepts of greater than 6.8 g/t. In 1993, Meridian Gold purchased all the precious metals rights to the property, without royalties, and expanded the deep exploration program. As of December 2002, the STORM resource is defined by 141 drill holes, 113 surface and 28 underground. In 60 of these holes, there are 91 intercepts of more than 1.5 meters, each of which grades better than 6.8 g/t. These 91 intercepts have an average thickness of 6.5 meters and a weighted average grade of 15.7 g/t Au. The STORM resource contains an inferred resource of 2.5 million tonnes at an average grade of 11.8 g/t Au, at a gold cutoff of 6.8 g/t, for 960,000

I bring you moons and snowy clouds, I bring you prairie skies to-night To feebly praise your golden eyes And red-bird song, and throat so white. To Gloriana -Nicholas Vachel Lindsay [1879-1931] The English word gold comes from a series of ancient words that refer to the color yellow. Its rarity, beauty and ability to be shaped by man have made it a highly desired precious metal throughout the history of mankind. "Gold fever" has been a frequently recurring affliction for humans. Today, artists and artisans use gold extensively in making jewelry and other objects of beauty. Also, because of its distinctive characteristics as a metal, gold has important uses in dentistry, photography, industry and electronics.

geology I regional geology I geology of Martha Mine geology of the waste disposal area Regional geology: a recipe for gold: a brief description of the geological history of the Waihi region. Volcanic Violence Around 20 million years ago volcanoes burst through the landscape around what we now know as Waihi. Tall, steep sided andesite volcanoes formed as the hot lava was thrown out to coat the sides of the volcanoes and the surrounding land. These volcanoes were similar in size and shape to Ruapehu and Ngauruhoe in the central North Island. Volcanic eruptions continued throughout the Coromandel for more than 15 million years. The Mountains Wear Down Any rock raised above the ground is subjected to a range of forces that gradually wear it away. Over time the forces of weathering and erosion can reduce mountains to hills. 20 million years of weathering and erosion has taken its toll on the local landscape. It is hard to make out the shape of those ancient volcanoes. Hundreds of metres of rock have been gradually eroded away from the original mountains. Other Forces Meanwhile, other forces were also working deep within the earth. The landmass of New Zealand was being squeezed and uplifted, helping the mountain building process. This uplift continues today, very slowly pushing up most of New Zealand.

intro geology gold silver ... Geothermal migration Regional geology: a recipe for gold: a brief description of the geological history of the Waihi region. Geysers, Mudpools and Gold The Waihi landscape was very different seven million years ago. The land was higher, probably by several hundred metres. Geysers threw boiling, mineral rich water high into the air, mudpools bubbled and hot springs dotted the countryside, very much like Rotorua today. Hot rock far below the ground provided heat energy for those spectacular features and also provided the ingredients for the gold deposit to be formed at Martha Hill. Over time the volcanic activity dwindled as the volcanic 'hot spot' gradually migrated southeast, passing through Tauranga and Te Puke to be centred around the Central Plateau today. Below is an impression of how the land has changed over the last 20 million years, showing how the forces of nature comine to produce a recipe for gold.
