山东省汶上县檀家楼铁矿矿床地质特征及找矿前景

Geological Characteristics and Prospecting Potential of Tanjialou Iron Deposit in Wenshang County in Shandong Province

摘要:

檀家楼铁矿床位于山东省汶上县城北，地处东平汶上铁矿带南段，属“鞍山式”沉积变质型铁矿床。可划分出磁铁矿化带5条，矿体均赋存于泰山岩群山草峪组中，共圈定出磁铁矿体21个，其中主矿体4个，倾向W，倾角65°～82°。矿床平均品位TFe 27.22%，mFe 17.65%。通过对檀家楼地区铁矿地质特征研究，大致查明了檀家楼铁矿床矿体的形态、产状、分布、厚度、矿石特征等。根据矿床成因、类型、矿床特点等，认为檀家楼地区铁矿找矿标志有地球物理、地层、矿体的赋存特征等3个主要标志。檀家楼矿区矿石品位普遍偏低，因此划分出较多的矿体，部分矿体不连续。

Abstract:

Tanjialou iron deposit is located in the north of Wenshang county in Shandong province. It si in the south of DongpingWenshang iron ore belt, and belongs to “Anshan type” sedimentary metamorphic iron deposit. The mine can be divided into five sections. The ore bodies occurrs in Shancaoyu formation of Taishan group. 21 magnetite ore bodies have been found, and 4 are main ore bodies with the trend of W，and the dip angle is 65°~82°. Average degree of TFe is 27.22%, and average degree of mFe is 17.65%. Through study on geological characteristics of iron ores in Tanjialou area, the shape, occurrence, scale, distribution, thickness and mineral characteristics of Tanjialou iron deposit have been identified. According to the origin, types and characteristics of the deposit, it is considered that there are three main indicators of iron ore prospecting in Tanjialou area, they are geophysical, stratigraphic and ore body occurrence characteristics.The grade of ore in Tanjialou iron deposit is generally low, so more ore bodies are divided, and some ore bodies are not continuous.
