Gold mineralization in the northern margin of the North

The petrologic and geochemical features of the studied alkaline rocks for gold mineralization imply that the studied NNCC gold deposits coexist with alkaline granitoids spatially and temporally. The granitoid rocks are suitable rocks that enhance structural pathways, thermal input, and thermodynamically strong conditions for gold deposition ( Li et al., 2015 ).

Gold Deposits and Their Geological Classification

2016-11-20  A rational geological classification of the commonly recognized lode gold deposits is feasible if it is based on the geological settings of the deposits, host rocks, nature of mineralization and geoche m-ical signature.

Structural geometry of orogenic gold deposits

2018-7-1  At the district to deposit scale, gold deposits may be hosted by a variety of faults or shear zones that pre-date gold mineralization: D1 and D2, less commonly D3, structures as evident in most published structural sequences (e.g., Vielreicher et al., 2016) typically defined by four or five distinct deformation episodes.
