Mineralogy and Geochemistry of Nephrite Jade from Yinggelike Deposit, Altyn Tagh (Xinjiang, NW China)
minerals Article Mineralogy and Geochemistry of Nephrite Jade from Yinggelike Deposit, Altyn Tagh (Xinjiang, NW China) Ying Jiang 1, Guanghai Shi 1,* , Liguo Xu 2 and Xinling Li 3 1 State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences, Beijing 100083, China; [email protected] 2 Geological Museum of China, Beijing 100034, China; [email protected] 3 Xinjiang Uygur Autonomous Region Product Quality Supervision and Inspection Institute, Xinjiang 830004, China; [email protected] * Correspondence: [email protected]; Tel.: +86-010-8232-1836 Received: 6 April 2020; Accepted: 6 May 2020; Published: 8 May 2020 Abstract: The historic Yinggelike nephrite jade deposit in the Altyn Tagh Mountains (Xinjiang, NW China) is renowned for its gem-quality nephrite with its characteristic light-yellow to greenish-yellow hue. Despite the extraordinary gemological quality and commercial significance of the Yinggelike nephrite, little work has been done on this nephrite deposit, due to its geographic remoteness and inaccessibility. This contribution presents the first systematic mineralogical and geochemical studies on the Yinggelike nephrite deposit. Electron probe microanalysis, X-ray fluorescence (XRF) spectrometry, inductively coupled plasma mass spectrometry (ICP-MS) and isotope ratio mass spectrometry were used to measure the mineralogy, bulk-rock chemistry and stable (O and H) isotopes characteristics of samples from Yinggelike. Field investigation shows that the Yinggelike nephrite orebody occurs in the dolomitic marble near the intruding granitoids. Petrographic studies and EMPA data indicate that the nephrite is mainly composed of fine-grained tremolite, with accessory pargasite, diopside, epidote, allanite, prehnite, andesine, titanite, zircon, and calcite. Geochemical studies show that all nephrite samples have low bulk-rock Fe/(Fe + Mg) values (0.02–0.05), as well as low Cr (0.81–34.68 ppm), Co (1.10–2.91 ppm), and Ni (0.52–20.15 ppm) contents. -

These units are host to a number of large VHMS deposits in the nearby area, including Rosebery Pb-Zn, Hellyer Zn-Pb-Ag-Au and the large copper deposits of the Mount Lyell field. The licence area has been the site of historical copper mining in the 1890’s to early 1900’s. Concerted modern exploration for base metal VHMS deposits has continued since the 1950’s. Following review of historical and 2 aeromagnetic data 51 kmP P has been identified as non-prospective and marked for release. 2 Introduction The Selina Exploration Licence 29/2002, a 24 km long by 5 km wide belt, is located in Western Tasmania, between Queenstown to the south and Rosebery to the north. EL 29/2002 is found on the Sophia (8014) and Franklin (8013) 1:100,000 map sheets, and initially covered an area of 2 109kmP .P Topography is rugged and varied, comprising steep timbered slopes with deeply incised valleys and gentler button grass marshland on elevated plateau’s and broad plains. -

Groundwaters in Wet, Temperate, Mountainous,Sulphide-Mining Districts
Groundwaters in wet, temperate, mountainous, sulphide-mining districts: delineation of modern fluid flow and predictive modelling for mine closure (Rosebery, Tasmania). by Lee R.

Three co-authored conference publications written as part of the present study (Evans et al., 2003; Evans et al., 2004a; and Evans et al., 2004b) are provided in Appendix Sixteen. Lee R. Evans Date: This thesis is to be made available for loan or copying in accordance with the Copyright Act 1969 from the date this statement was signed. Lee R. Evans Date: ii Abstract There are as yet few studies of the hydrogeology of sulphide-mining districts in wet, temperate, mountainous areas of the world. This is despite the importance of understanding the influence of hydrogeology on the evolution and management of environmental issues such as acid mine drainage (AMD). There is a need to determine whether the special climatic and geological features of such districts result in distinct groundwater behaviours and compositions which need to be considered in mining impact studies. -

Rdosdladq1//6Lhmdq`knesgdLnmsg9@bshmnkhsd This month’s featured mineral has many interesting and unusual varieties: While our specimens have well-developed prismatic crystals, which is unusual for actinolite, a fibrous variety is a former ore of asbestos, and a microcrystalline variety is one of the two types of the gemstone jade. Read on! OGXRHB@K OQNODQSHDR 2+ Chemistry: GCa2(Mg,Fe )5Si8O22(OH)2 Basic Calcium Magnesium Iron Silicate (Calcium Magnesium Iron Silicate Hydroxide) Class: Silicates Subclass: Inosilicates (Double-Chain Silicates) Group: Tremolite (Amphibole Group) Crystal System: Monoclinic Crystal Habits: Usually long prismatic with diamond-shaped cross section; also bladed, columnar, acicular, divergent, fibrous (asbestiform), and radiating. A compact, microcrystalline form is known as nephrite jade. Color: Bright-to-dark green, grayish-green, and greenish-black. Luster: Vitreous; silky and pearly on cleavage surfaces. Transparency: Transparent to translucent Streak: Colorless to white Cleavage: Perfect in two directions lengthwise with intersecting cleavage planes. Fracture: Splintery, uneven; fibrous forms are flexible. Hardness: 5.0-6.0, nephrite variety is 6.5. Specific Gravity: 3.0-3.5 Luminescence: None Refractive Index: 1.63-1.66 Distinctive Features and Tests: Best field marks are the prismatic, often-radiating crystal habit and narrow cleavage-intersection angle. Can be confused with wollastonite, which is fluorescent; the tourmaline-group minerals, which lack cleavage; and epidote, which has a broader cleavage angle. Laboratory methods are necessary to differentiate actinolite from tremolite and ferro- actinolite, as explained in the box on Page 3. Dana Classification Number: 66.1.3a.2 M @L D The name “actinolite,” pronounced ack-TIH-no-lite, derives from the Greek aktino, meaning “ray,” a reference to the common radiate habit of its prismatic crystals. -
