乐旺大理石矿床位于望谟县城北东54Km,通公路,交通方便。矿床东西长1400m,南北宽1000m,矿层裸露程度好,矿体单层厚度大,质地优良,主要大理石品种为墨雪和白筋黑。经初步调查证实规模可观,颇具开发利用前景。 一、矿床地质 (一)地层 矿区出露地层见图1。大理石产于半局限海台地下二叠统茅口组中。 (二)地质构造 矿床位处黔南台陷望谟北西向构造变形区,打狼弧形背斜之北西翼,为一单斜构造。出露地层由南东向北西依次为下二叠统茅口组、上二叠统吴家坪组。地层倾向北西,倾角20—50°,一般35°。构造简单,未见明显的断层,节理有四组:
Lewang marble deposit is located in Wangmu County, north-east 54Km, access roads, and convenient transportation. The deposit is 1400m long in east and west and 1000m wide in north-south. The ore is bare with a large thickness of monolayer and the texture is excellent. The main marble varieties are Moxue and Baijian black. After a preliminary survey confirmed that the scale is considerable, considerable development and utilization prospects. First, the geological deposit (a) stratum exposed mine strata shown in Figure 1. Marble produced in the semi-confined sea platform Permian Maokou group. (B) geological structure Deposit is located Qiannantai Banmo Northwest tectonic deformation zone, playing wolf arc anticline north west wing, a monoclinic structure. The exposed strata from south to east to northwest followed by Lower Permian Maokou Formation, Upper Permian Wujiaping Formation. The strata tend northwest, dip 20-50 °, the general 35 °. Simple structure, no obvious fault, joint has four groups:
