这里所谓的川西红盆是指:北西起于芦山双石～灌县,南东止于蒲江经成都至广汉,南起天全,北抵什邡,面积约一万平方公里的范围(图一)。 早在六十年代后期,川地101队,就在本区开展盐矿普查,前后工作达十年之久,共施工钻孔35个,总进尺20322米(未计外单位施工的近20个钻孔),除探明巨大数量的钙芒硝矿石外,始终未发现固体岩盐。一致的结论是本区只达到硫酸盐沉积阶段,未沉积岩盐。
The so-called Kawanishi basin refers to the northwest starting from Lushan Shuangshi to Guanxian, and the south ends only from Pujiang to Chengdu and Guanghan. From the south to the sky and the north to Shifang, it covers an area of about 10,000 square kilometers (Figure 1). As early as the late 1960s, the 101 team of Sichuan to carry out salt mine census in this area, before and after work for ten years, a total of 35 borehole construction, the total footage of 20322 meters (not counting the construction of nearly 20 units Drilling), in addition to the discovery of a large number of glauberite ore, the solid rock salt has not been found. Consistent conclusion is that the area only reached the stage of sulfate deposition and did not deposit rock salt.
