Cathodoluminescence and Trace Elements in Quartz: Clues to Metal Precipitation Mechanisms at the Asachinskoe Gold Deposit in Kamchatka Ryohei Takahashi1,*, Axel Müller2, Hiroharu Matsueda3, Victor M. Okrugin4, Shuji Ono5, Alfons van den Kerkhof 6, Andreas Kronz and Elena D. Andreeva4 ABSTRACT
Textures of hydrothermal quartz revealed by cathodoluminescence using a scanning electron microscope (SEMCL) reflect the physical and chemical environment of quartz formation. Variations in intensity of SEMCL can be used to distinguish among quartz from superimposed mineralization events in a single vein. In this study, we present a technique to quantify the cathodoluminescent intensity of ...

Mar 13, 2018· Quartz has a massive crystalline appearance and can be white, yellow, pink, purple, grey or black. Gold occurs in between the other crystals found in quartz. Look for gold in quartz veins in areas where the bedrock is fractured by tectonic and volcanic activity.
This property is likely a major gold deposit and has considerable potential for a multimillion ounce discovery. Summary (1) Several hundred rock samples containing visible gold in quartz, quartz breccia and iron formation have been reported from various properties and mine dumps in the Lost Basin District of Northwestern Arizona.
