2007-5-9 · These large porphyry‐type deposits conform to a single overall model, whereas the large epithermal gold deposits are varied in both genetic type and mineralisation style. Most regional and local characteristics of the largest porphyry and epithermal deposits fail to explain convincingly their extremely high gold contents.

Characteristics that distinguish types of epithermal deposits

Three distinctive groupings of epithermal deposits were recognized from a literature study of fifteen well-described precious- and base-metal epithermal districts, supplemented by L. J. Buchanan's 1981 compilation of data from 47 less completely documented deposits. The three groups are distinguished primarily by the type of alteration and the sulfur fugacity indicated by the vein mineral ...

In the Biga peninsula the Tethyan Metallogenic Belt is represented by a Neo-Tethyan suture zone. Discovered deposits along the belt are commonly associated with Cenozoic magmatism ranging between 52 and 18 Ma in age, formed due

The quartz veins in low-sulfidation epithermal deposits exhibit a wide range of textural characteristics [14,15,16,17].Previous works [16,18,19,20] have proposed that some of the quartz textures encountered in epithermal veins are of secondary origin and

Characteristics and Genesis of Epithermal Gold Deposits

Intermediate-sulfidation epithermal deposits occur in a broadly similar spectrum of andesitic-dacitic arcs but commonly do not show such a close connection with porphyry Cu deposits as do many of the high-sulfidation deposits. However, igneous rocks as silicic as rhyolite are related to a few intermediate-sulfidation deposits.
