山东高岭土矿成矿特征及成矿规律探讨

Study on Metallogenic Characteristics and Regularity of Kaolin in Shandong Province

摘要:

山东省已发现高岭土矿床18处，分为沉积型和风化残积型2种类型。沉积型高岭土矿受沉积作用的控制，石炭系—二叠系是其主要赋矿层位，广泛发育于鲁中地区北部的各煤田中。风化残积型高岭土矿则以中、小型矿床和矿点的形式零星分布于鲁南和鲁东各地。本文总结了山东省高岭土矿的成矿特征和成矿模式，通过典型矿床详细介绍了高岭土矿的矿体特征和矿石特征，在山东高岭土矿成矿区带（Ⅳ级）中，主要圈定4个找矿远景区，明确了山东省高岭土矿的勘查方向。

Abstract:

There are 18 kaolin deposits in Shandong province, which can be divided into sedimentary type and weathered residual type. The sedimentary kaolinite is controlled by sedimentation, and the Carboniferous—Permian system is the main ore bearing horizon, which is widely developed in various coal fields in the north of central Shandong province. The weathering residual type kaolinite deposits are scattered in the form of small and medium sized deposits and ore spots in the south and east of Shandong province. Metallogenic characteristics and metallogenic model of kaolin mineralization in Shandong province have been summarized in this paper, and characteristics of ore and ore bodies of kaolin deposits have been introduced in detail. In the metallogenic belt (grade IⅣ) of kaolin deposits in Shandong province, 4 ore concentration areas are mainly delineated. On this basis, exploration direction of kaolin deposits in Shandong province in the future has been clarified.
