摘要
鲁中隆起的北缘分布着100多个燕山期的碳酸岩体。本文详细研究了岩体中磷灰石的一些重要特征,包括晶体形态、物理性质、光学常数、晶胞参数、化学成分、包裹体及钕锶同位素组成等。并据所得资料对岩体的成因,成岩物质来源等问题进行探讨。
More than one hundred of Yanshanian carbonatites are distributed in the northern fringe of the central part of Shandong Province. The characteristics of apatite in the rocks,such as the crystal form,physical property,optical constant,unit cell parameter,chemical composition,inclusion,and Sr-Nd isotopes are researched and measured, Based on the data obtained, the petrogenesis of carbonatite and original diagenetic materials are also investigated.
