河台金矿 

河台金矿（产于元古宙变碎屑岩、泥质岩、碳酸盐岩中的金矿构造蚀变岩型亚类）。

河台金矿发现于1982年7月，位于高要县境内。它的发现，为在华南地区前泥盆纪地层，特别是混合岩化变质岩系中寻找同类矿床提供了范例。

在大地构造位置上，矿区位于吴川－四会断裂带与那蓬－悦城断裂带的交汇部位，矿区由震旦系Ｃ组混合岩化片岩、变粒岩、片麻岩、混合花岗岩组成，南侧为志留系和奥陶系浅变质的复理石建造。两者呈断层接触，含金千糜岩带赋存于断层北侧的混合岩化岩石和混合岩内（图4）。Zc 组岩石主要有二云母石英片岩、云母片岩和少量黑云母变粒岩、片麻岩等。片岩中普遍含夕线石。由于混合岩化作用普遍，因此常见新生的斜长石和微斜长石呈眼球状沿片理分布。

River gold deposit
Hetai Gold (gold deposit tectonic alteration produced in Proterozoic metamorphic clastic rock, mudstone, carbonate rock type in the subclass).
He found in July 1982, located in the territory of the county. It is found that, in the South China area pre Devonian strata, especially migmatization metamorphic rock series in looking for similar deposits provides an example.
On the tectonic position. The mine is located in the Wuchuan - Sihui fracture band and that Peng - Yue City fracture with the intersection, mining area by Sinian C group migmatite schists, granulite and gneiss, mixed granite composition, on the south side of the Silurian and Ordovician shallow metamorphic flysch, stone built building. There is gold bearing fault contact, phyllonite zone occurs in the fault on the north side of the migmatitic rocks and mixed rocks (Figure 4). Group Zc rocks mainly have two mica quartz schist, mica schist and minor biotite granulite gneiss, etc.. Sillimanite commonly contain schist. Due to widespread migmatization, so common new plagioclase and microcline was augen along foliation distribution.
