月河自西向东流去,两侧支流发育。南岸支流短而陡,多为间歇性水流;北岸支流长而缓,为常年性流水。盆地内新构造运动十分明显,周期性的升降运动,形成了Ⅰ-Ⅳ级阶地。
大同矿段是该流域典型矿段之一。东西长9000多m,南北宽500~1100m,已圈定出金矿体和矿化区10余个。矿体平面上呈长条状,剖面上呈似层状,沿河床两侧展布。单个矿体( 矿体区)长600~6000多m,厚3.37~5m多,含金品位0.078~0.378g/m3,盖层厚1.92m。
The river from west to East, tributaries on both sides of the development. The south bank is short and steep, many are intermittent flow; the north shore of the river is long and slow, for the perennial water. The new tectonic movement in the basin is very obvious, the lifting movement periodicity, form I - IV terrace.
Datong mine section is one of the typical ore deposits in the basin. Something more than 9000 m long, north-south width of 500 ~ 1100m, has delineated the gold ore body and mineralized area of more than 10. The ore body is in the shape of a long strip, and the profile is layered, along the river bed. Single ore body (ore body area) 600 to 6000, more than m, 3.37 ~ 5m thick, gold grade 0.078 ~ 0.378g/m3, cover thickness 1.92m. |
