2.3 Granite-related mineral system Geoscience

2021-5-5  An unusual deposit that may be part of the granite-related mineral system is the Mary Kathleen deposit in northwest Queensland, which was mined for U until the 1970s. This deposit, which produced over 10 kt U 3 O 8,is a garnet-pyroxene skarn most likely associated with emplacement of the ˜1740 Ma Burstall Granite

Classification of Mineral Deposits Geology for Investors

2013-7-29  Most mineral deposits are formed by more than one process, so attaching a single label to them is difficult. Hence, there is a tendency to talk about Stillwater Complex type or Carlin-type gold deposits, which rather defeats the purpose of finding a general from the specific. There are two main approaches to mineral deposit

Granite: Igneous Rock Pictures, Definition & More

What is Granite? Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals.This mineral composition usually gives granite a red, pink, gray, or white color with dark mineral

Formation of a Magmatic-Hydrothermal Ore Deposit:

1998-3-27  The physical and chemical mechanism of ore precipitation in the Yankee Lode tin deposit (Mole Granite, Australia) was quantified by direct trace-element microanalysis of fluid inclusions. Laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) was used to measure element concentrations in a series of fluid inclusions representing the fluid before, during, and after the

Petrogenesis of the Xihuashan Granite in Southern

The Xihuashan granite is a typical representative of tungsten-bearing granite. The Xihuashan granite consists mainly of medium-grained porphyritic biotite granite, medium-grained biotite granite and fine-grained two-mica granite, which correspond to LA-ICP-MS zircon U-Pb ages of 155.5±0.4 Ma, 153.0±0.6 Ma and 152.8±0.9 Ma, respectively.
