查明地质体的数学特征,建立地质体的数学模型是数学地质最基础的研究课题之一,而研究和查明矿体的数学特征又具有重要的理论和实际意义。地质标志的数学特征可概括为几何特征、统计特征、空间特征和结构特征等四类。本文仅就所研究矿体的空间特征作一介绍。本文所研究的矿床为一外接触带层间夕卡岩型矿床。矿化与燕山期花岗岩有关。矿体赋存于寒武—奥陶系结晶灰岩及斑点板岩的层间夕卡岩内,受层间剥离及断裂构造控制。矿区中部沿接触带分布有大片无矿夕卡岩,它将层间夕卡岩中的矿体分为岭前及岭北两个矿段,矿体延长和延深均达数百米,厚度一般为几米
Identifying the mathematical characteristics of geologic bodies and establishing the mathematical model of geologic bodies are one of the most basic research topics in mathematical geology. It is of great theoretical and practical significance to study and identify the mathematical characteristics of ore bodies. Geological signs of mathematical characteristics can be summarized as geometric characteristics, statistical characteristics, spatial characteristics and structural characteristics of four categories. This article only describes the spatial characteristics of the ore bodies studied. The deposit studied in this paper is an outer contact zone skarn deposit. Mineralization and granite Yanshan period. Ore bodies occur in interlayer skarns of Cambrian-Ordovician crystalline limestone and speckled slate, controlled by interlayer delamination and fault structure. There are a large number of ore-free skarn along the contact zone in the middle part of the mining area, which divides the ore bodies in the skarns of the strata into two ore blocks, Lingqian and Lingbei. The ore body extends and extends for several hundred meters in thickness, and the thickness Generally a few meters
