在整理东海重矿物资料过程中,发现重矿物分析数据虽有一定的规律性和区域分布特征,但是在进行具体矿物组合类型划分和按地理分布分区时,就感到难以确定。同样的原始数据,凭个人经验得出的结果很不一致,有时甚至相反,给资料的对比和应用以及进一步研究造成困难。另一方面,原始分析数据的关系十分复杂,定性地探讨整个东海海区矿物间的
In the process of sorting out heavy minerals in the East China Sea, heavy minerals analysis data are found to have certain regularity and regional distribution characteristics, but it is difficult to determine when the specific mineral combination types are divided and geographical distribution is conducted. The same raw data, based on personal experience, result very inconsistent, and sometimes even the opposite, to the comparison and application of data as well as further research difficult. On the other hand, the relationship between the original analytical data is very complicated, qualitatively exploring the mineral inter-mineral
