Geological condition of Macaotan phosphorite deposit and the prospectiveness of its surrounding area are discussed.1. Phosphorite formation overlies upper Sinian dolomite, which was subfected to a prolonged erosion. Thickness of ore formation is derectly determined by paleotopography. Correlation factors between them are analyzed via statistic regression, where thickness of ore formation is regarded as a random variation.2. A series of secondary folds of NE trend, which are parallel to a major jold,...

Correlation factors between them are analyzed via statistic regression, where thickness of ore formation is regarded as a random variation.2. A series of secondary folds of NE trend, which are parallel to a major jold, uplift the phosphorite formation in places to the level of erosional surface and make it easy for mining.3. Prospectiveness of the surrounding area is predicted and proved by exploration project.

马槽滩磷矿含磷层假整合于震旦系上统白云岩古喀斯特凹凸侵蚀面之上,矿体厚度直接决定于古地形。采用回归法分析了矿体厚度与古地貌之间的关系,据统计研究,矿体厚度属随机变量。矿区深部构造为一系列走向北东,平行于主褶皱的次级褶皱。次级褶皱的发育使含磷层上升于侵蚀面之上,从而有利于开采。根据地质特点,对矿区外围远景作了预测,勘探结果已初步证实其可靠性。

This paper deals with distribution of the sedimentary facies and ore deposits of Hubei province which may be controlled by tectonic elements, especially by the growth faults in long period.The studied region includes three sedimentary enviroments, they are shelf marginal basin of northern Hubei, platform shelf region of central Hubei and the deep-water shelf of southern Hubei.These environments are graben-type basins, separated by two deep fracture zones and some vanadium and uranium, barite, phosphorite...

This paper deals with distribution of the sedimentary facies and ore deposits of Hubei province which may be controlled by tectonic elements, especially by the growth faults in long period.The studied region includes three sedimentary enviroments, they are shelf marginal basin of northern Hubei, platform shelf region of central Hubei and the deep-water shelf of southern Hubei.These environments are graben-type basins, separated by two deep fracture zones and some vanadium and uranium, barite, phosphorite occur the northern and southern deep-water regions, along faults, however, in the central Hubei platform only layered phosphorite deposits occurred.The distribution of blackshale series of early Cambrian in China and even throughout the world are very broadly.The author believed that the paleoclimate of early Cambrian in the worldwide was humid, oxygen-poor, and rich in CO_2, subsequently numerous small shelly fossils replenish the biosphere, as well as the large amounts of meteoric dust fell in earths surface, all of which led to particular paleoclimare and paleogeography of early Cambrian, and to be formed significant black rock series.

本文从岩相古地理分析出发,探讨了沉积环境、同生断裂与某些沉积矿床的内在联系。为该区岩相分析及找矿提供了信息。

The study area is located on the southwest of Kunming and the west of Dianchi Lake in the eastern Yunnan, where is an important phosphorous producting area in China. Two phosphorous deposits are involved in this area (Fig. 1) - the Kunyang phosphorite deposits and the Haikou phosphorite deposits. They are well known for the great reserves and outstanding quality.

本文阐明滇东早寒武世昆阳、海口磷矿沉积于牛首山古陆及滇中古陆之间的海湾泻湖环境,有利于两侧的深海槽盆洋流上升,可以将分散磷质不断带到浅水海湾之中;具有高本底值磷质的古陆,由于迳流也提供一定的磷质;由于磷质及其它生命元素源源不断供给,使得温暖、浅水海湾的菌、藻生物大量繁殖,有效地固定了海水中分散的磷质并沉聚于海湾底部沉积物中。昆阳磷矿与海口磷矿之间近东西向水下隆起的存在,从搅动的浅水产生磷质沉积物的簸选,导致较粗的颗粒磷块岩的富集。经过早期成岩阶段的酶、菌作用,使孔隙水中磷质聚集形成胶结物,进一步使颗粒磷块岩品位更富。
