本文对利用微量元素来区分沉积环境提出了一种新的方法:即利用沉积岩中微量元素的含量组合,在概率图解中找出相区,以判别沉积环境。其基础是:一定的地质体中,化学元素含量成一定型式的概率分布。用这种方法来判别广东东部中生代地洼盆地早侏罗世地层的沉积环境时,是可行和有效的。并得出如下规律性的认识:海相沉积物的微量元素含量组合的平均值对标准差的比值小,而陆相沉积物的比值大。
In this paper, we propose a new method to distinguish the sedimentary environment by using trace elements. By using the combination of trace elements in sedimentary rocks, we can find out the phase area in the probability diagram to distinguish the sedimentary environment. The basis is: a certain geological body, the chemical element content into a certain type of probability distribution. It is feasible and effective to use this method to discriminate the sedimentary environment of the Early Jurassic strata in the Middle-Lower Depression of the Mesozoic in Guangdong Province. And came to the following regularity: the average ratio of the trace element content of marine sediments to the standard deviation is small, while the ratio of continental sediments is large.
