Vein (geology) - Wikipedia

In many gold mines exploited during the gold rushes of the 19th century, vein material alone was typically sought as ore material. In most of today's mines, ore material is primarily composed of the veins and some component of the wall rocks which surrounds the veins.. The difference between 19th-century and 21st-century mining techniques and the type of ore sought is based on the grade of ...

RESIDUAL & ELUIVIAL GOLD PLACER EXAMPLE - GOLD …

Jan 11, 2013· Eluvial gold placers usually represent a transitional stage between a residual placer and a stream placer. Where one type merges into another, they cannot be clearly distinguished. They are characteristically found in the form of irregular sheets of surface detritus and soil mantling a hillside below a vein or other source of valuable mineral.
