惠安花岗石的不同尺度的节理研究

节理是花岗石中普遍存在的构造形迹，通过对惠安岩体东南部的不同尺度节理进行的研究，认识到以主期节理为主导的一般节理系是控制惠安花岗石的成块性和风化露头形态的构造因素；微型节理与一般节理具有明显的相似性，微型节理组成多样式的节理图案，在花岗石抛光面上形成暗线、暗斑，影响花岗石的光泽度。因而，在石材的评价、开采和加工中不同尺度的节理研究是不可忽视的构造地质学问题。

STUDY ON THE DIFFERENT-SCALE JOINTS IN HUIAN GRANITE

By studing the different-scale joinjts in southeast Huian granite rock mass it is known that the or-dinary joints are main factors controlling the lumpiness and weathering outcrop shape of the Huiangranite;the micro-scale joints compose multiple patterns and form many dark lines and spots on thepolishing surfaces of the granite- Therefore, it is important to study the different-scale joints in graniterock material.
