The Influence of Late Triassic volcanism on the development of Chang 7 high grade hydrocarbon source rock in Ordos Basin
晚三叠世火山活动对鄂尔多斯盆地长7优质烃源岩发育的影响
The change of volcanic rocks from marine facies to continental facies and change of volcanism from strong to weak indicate that after the Permian the upper mantle materials had long been in a constrictive stage,and that the whole basin sank continuously to receive deposits,thus resulting in crustal thickening.
准噶尔盆地被古生代缝合线构造包围,周缘山系向盆地方向逆冲推覆,显示了盆地处于长期受压的构造环境;火山喷发由海相转变为大陆相,火山活动由强到弱,表明二叠纪以后,上地幔物质一直处于收缩状态,盆地整体持续下沉接受沉积,地壳增厚。
The authors have deeply realized the great significance of volcanism in the formation of gold deposits through many years of work in areas of volcanic rocks and arrangement and analysis of geological data of large and superlarge gold deposits at home and abroad.

结果表明,阳信洼陷火成岩特别发育,火成岩的形成与分布主要受断裂活动的影响,同时火山活动对盆地演化、油气生成、圈闭形成和油气成藏具有一定的控制作用。
Through analyses of tectonic geomorphic features in Tengchong region (24°40′～25°30′N,98°15′～98°45′E), it is considered that the local tensile stress environment existing from the Pliocene is an important factor for the volcano activity.
通过对腾冲地区 (2 4°4 0′～ 2 5°30′N ,98°15′～ 98°4 5′E)构造地貌的分析 ,认为上新世以来本区存在的局部张应力环境是火山活动产生的重要因素。
We get the conclusion that both geochemistry method and the routine gas analysis can reflect the information of volcano activity and earthquake activity,and both of them can play an important role in prediction of volcano eruption.
本文回顾了流体地球化学方法在活动火山监测中的历史,重点分析了长白山火山监测站温泉逸出气体成分变化与火山活动的对应关系,得出了无论是同位素地球化学方法还是常规的温泉逸出气体检测方法,观测结果都很好地对应了火山及火山地震的活动,可以在火山喷发预报中发挥重要的作用。
Based on the ages of 76 samples of rocks and the comparison of 107 drill hole sections, the volcanicity can be pided int.
本文根据７６个岩石样品的年龄和１０７个钻孔剖面的对比，认为本区第四纪火山活动可分为６期，并具有以喷溢为主、多旋回、从海相向陆相转变的特点。
