Gold, Quartz & Chalcedony—Part II
November 2011 by W. Dan HauselThe specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
Ivory Coast has considerable gold reserves, and this nation has the largest area of greenstone belts prospective for gold in the continent.
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
Trinity County is located in the far northwest corner of California and stirs up many different memories for those who have been there.
