Abstract

With high-grad scandium and anatase ore deposit of Qinglong Shazi and three typical laterite gold deposit of Laowanchang, Baozidong and Shaguochang in western Guizhou as research objects, this paper makes a comparative analysis on character of mineral geology. There are both similarities also differences of the geologic features between anatase and gold deposit with the specific explanations are as follows: 1) Both high-grad scandium and anatase ore deposit and laterite gold deposit are occurred in the laterite of the quaternary slope sand on the plane of unconformity of Permian Maokouan limestone karst; 2) Both high-grad scandium and anatase ore deposit and laterite gold deposit are originated from the relatively broad and gentle anticlinal cores and flanks with the anticlinal core composed of the middle Permian Maokou formation stratum and the flank composed of the stratum of Emeishan basalt and Longtan formation; 3) Both high-grad scandium and anatase ore deposit and laterite gold deposit occurred in the local Karst esker knobs with high altitude and the mini-type depression on the gentle slope; 4) Ore characteristics and mineral composition are mainly the same in the high-grad scandium and anatase ore deposit and laterite gold deposit. The difference lies in no anatase has been found in those three typical kinds of laterite gold deposits and no micro-fine particle of Au has been detected in the high-grad scandium and anatase in Qinglong Shazi ore deposit.Mantle plume active region in Emei is the important concentration zone of super- large and large ore deposit [1-4]. Taking basalt region in the west of Guizhou as an example, mineral products like gold, antimony, copper, arsenic, mercury, thallium, rare earth have produced here [5-7]. In recent years, large-scale high-grad scandium and anatase ore deposit has been founded in the Qinglong Shazi in Guiyang [8]. The genetic type of large-scale high-grad scandium and anatase ore deposit in the Qinglong Shazi belongs to the thermal water deposit- slope deposit related with basalt eruption of Emei. The orebody occurred on the plane of unconformity of Permian Maokouan limestone karst and in red clay of the Karst negative terrain on the bottom of Emeishan basalt, of which the occurrence space is the same with red-clay gold mineral in the west of Guizhou province. However, the high-grad scandium and anatase ore can’t be found in red-clay gold deposit and vice versa. Therefore, this paper aims at make a comparative analysis of the high-grad scandium and anatase ore deposit of Qinglong Shazi and three typical laterite gold deposit of Laowanchang, Baozidong and Shaguochang in western Guizhou, so as to discuss the differences the minerogenetic conditions between high-grade scandium and anatase ore deposit of Qinglong Shazi and three typical laterite gold deposit of Laowanchang, Baozidong and Shaguochang in west of Guizhou.
