红海热卤水及其富含重金属沉积,是迄今为止人们知道的唯一一个成矿卤水与所形成矿床共存的例子.对此我曾作过系统介绍(《国外地质》1974年第12期),现在拟就1971年以后的研究进展补充介绍如后. 1.除以前报道的《大西洲Ⅱ》、《发现》、《链条》三个热卤水洼地外,沿红海轴心海槽又发现了许多类似的洼地,总数超过13个.这说明它不是一种个别的、偶然的地质现象.但是,规模最大而且发现富含重金属沉积的仍然只是《大西洲Ⅱ》洼地. 2.从1964年首次测定卤水温度以来,《大西洲Ⅱ》洼地的卤水温度一直在上升,七十年代初期其最高温度近 The Red Sea hot brine and its heavy metal-rich sediments are by far the only examples of ore-forming brines that co-exist with the formed deposits, and I systematically introduced them (“Foreign Geology”, No. 12, 1974) and now It is intended to supplement the research progress made after 1971. 1. Besides the previously reported “hot springs” such as “Asiasu Ⅱ”, “discovery” and “chain”, many similar researches have been found along the axis of the Red Sea axis Of the total of more than 13. This shows that it is not an isolated and accidental geological phenomenon, but the largest and found to be rich in heavy metal deposits are still only “Akesu Ⅱ” depression. 2. From 1964 the first determination of brine Since the temperature, the brine temperature in the depression of the “Greater Western Ⅱ” has been on the rise. In the early 1970s, the maximum temperature was near
