通过运用古地磁学各种手段对76个古地磁样品的实验测试与数据处理,象其它测试实验研究方法一样,进一步说明了地幔岩部分熔融残体与其衍生岩浆岩不仅在各学科范围内显示一定的差异性,而且在古地磁学特征领域中亦具有很大的差别。例如西准噶尔地区在古地磁极位置方面,表现于纬度上相差10-30°,甚至更大。根据国内外有关资料分析,笔者初步认为该区地幔岩部分熔融残体团块的形成时代可能属于早古生代早期,甚至更早。然而地幔岩衍生的超基性岩浆岩等的形成时代可能属于石炭纪。其中唐巴勒地区的超基性岩略早一些,可能为志留纪,达拉布特地区的可能属于泥盆纪,只有萨尔托海地区的相对略晚一些,可能属于石炭纪前后。同时笔者还得出了它们相应地质时期的古纬度等资料。根据已取得的数据及初步认识,文中进一步概述了它们的演化过程及运动学模式,说明研究地区的构造运动是较强烈的,它们经历了大规模地移位,其距离可达数千公里。
Experimental and data processing of 76 paleomagnetism samples by various means of palaeomagnetic geology, as well as other test and experimental methods, further illustrate that some of the mantle rock and its derived magmatic rocks not only show a certain range of disciplines But also has great difference in the field of paleomagnetic features. For example, the area of ancient Junggar in western Junggar shows a difference of 10-30 ° or more in latitude. According to the relevant data analysis at home and abroad, the author preliminarily believes that the forming age of some molten residual clumps in the mantle rock may belong to the early Paleozoic, even earlier. However, the formation age of mantle-derived ultramafic magmatic rocks may belong to Carboniferous. Among them, the ultrabasic rocks in the Fontanelle are slightly older, possibly Silurian, and the Dalbott area may belong to the Devonian. Only the relatively a bit late in the Salto Sea may belong to the Carboniferous. At the same time I also come to their corresponding ancient geological latitude and other information. Based on the obtained data and preliminary understanding, the evolution process and kinematics model are further summarized in this paper. The tectonic movement in the studied area is more intense. They have undergone a large-scale displacement with a distance of thousands of kilometers.
