Altered mylonite and quartz vein type gold deposit, hosted in a regional ultra-ductile shear zone. The altered mylonite ore bodies are larger than the quartz vein type ore bodies, but have lower average grades.
The ore bodies are mostly parallel to shear planes and are 1.2 to 6.0 m thick with an average thickness of 3.5 m. Ore bodies are predominantly located at shear zone bends, dilational jogs, and contacts between rocks with different competencies.
Model: orogenic quartz vein gold deposit
The Jinshan gold deposit is specifically hosted in the subordinate, nearly EW-trending Jinshan-Xijiang ductileโbrittle shear zone, with kinematic indicators suggesting sinistral strikeโslip motion synchronous with Middle Jurassic (ca. 167โ161 Ma) regional tectono-magmatic events. Ore-hosting strata consist of the Mesoproterozoic Shuangqiaoshan Group, a greenschist facies metavolcaniclastic sequence striking 110โ150ยฐ and dipping 10โ35ยฐ NW. This group is subdivided into three lithostratigraphic: (1) the lower segment (Pt3shIIIโ1), ~300 m thick, comprises carbonaceous, sericite-, quartz-, and chlorite-bearing slates dominant in the southern orefield, constituting ~20% of the area and bounded by shear contacts; (2) the middle segment (Pt3shIIIโ2), the principal ore host (~500 m thick in the mine area), consists of tuffaceous, sandy, and silty phyllites intercalated with lenticular metabasalts, distributed in the northwestern and central sectors and in fault contact with the lower unit; and (3) the upper segment (Pt3shIIIโ3), >300 m thick, is characterized by medium- to thick-bedded gray silty slates with interbeds of sandy slate, tuffaceous slate, and metasandstone, occurring in the northeastern area and delimited by shear planes from the middle segment. The NE-trending F6 fault bisects the deposit into the western Wanjiawu segment and eastern Yangshan segment. Mineralization manifests as altered-rock (disseminated) style dominant in Wanjiawu (3โ10 g/t Au) and auriferous quartz-vein style prevalent in Yangshan (5โ20 g/t Au), both controlled by progressive ductileโbrittle deformation within the shear zones. Six principal orebodies are delineated: I and II in the Wanjiawu shear zone, and IIIโVI in the Yangshan shear zone, collectively accounting for the ~200 t Au endowment.
The hydrothermal processes related to the mineralization in the Jinshan gold deposit can be divided into four stages:(1) quartz (Q1)-carbonate, (2) pyrite-quartz (Q2), (3) gold-polysulfide-quartz (Q3)-carbonate, and (4) carbonate-chlorite-quartz.
The Yangshan ore block is mainly quartz vein- type mineralization, and the gold grade is between 5 g/t and 20 g/t. A total of six main ore bodies are delineated in the deposit. These ore bodies are tabular and lenticular and occur in the phyllonite, mylonite and ultramylonite in the shear zone, parallel to the main shear plane. Ore bodies I and II occur in the NW trending Wanjiawu shear zone, and ore bodies III, IV, V and VI (the main orebody) occur in the NE trending Yangshan shear zone.
The ore bodies are mostly parallel to shear planes and are 1.2 to 6.0 m thick with an average thickness of 3.5 m. Ore bodies are predominantly located at shear zone bends, dilational jogs, and contacts between rocks with different competencies.
