This suggests that mare-type volcanism must have occurred at least as early as this date, just after the first stage of lunar crust formation, say the authors, led by Dr Kentaro Terada of Hiroshima University in Japan and Dr Mahesh Anand of the UK's Open University .

研究的发起人日本广岛大学的 Kentaro Terada 博士和英国开放大学的 Dr Mahesh Anand 指出：这肯定地说明了，形成月海的火山作用起码不比这个时间更晚，就发生在月球外壳形成的第一阶段之后。

From on minerogenetic epoch, major take formed permocarboniferous period, very few has early palaeozoic; On the minerogenetic tectonic enviroment, major located on the rigidity basement of lie concealed, formed Igneous Instrusion and Volcanism of orogenic cycle.

从成矿时代看，多数矿床形成于石炭－二叠纪，少数形成于早古生代，成矿构造环境多数位于有隐伏刚性基底之上，形成于造山旋回构造岩浆活化带。

This paper has mainly dealt, with the structural setting of volcanism, the petrologic and geochemical characteristics of volcanic rocks and its related mineralization along the coast of southeastern China and its vicinity.

本文主要论述中国沿海及其邻侧火山作用的构造背景、火山岩的岩石学和地球化学特征，以及其有关的成矿作用。

This paper discusses the merits and shortcomings of the estimation methods previously used for the degree and mass of magma degassing in the volcanic eruption. On the basis of these methods, the authors propose a new petrological method for the estimation performed at various stages in the process of volcanism, and illustrate the detailed steps as exemplified by the Jingpohu Holocene volcanic eruption.

本文对前人使用的火山喷发过程中岩浆脱气率和脱气量的估算方法进行了评述，并介绍了如何利用岩石学方法估算火山喷发不同阶段岩浆脱气率和脱气量的具体步骤，同时以镜泊湖地区全新世火山为例说明利用该方法估算的具体过程。

The time span of the Xiaochaka Formation has also been constrained by related biostratum in present paper. It is inferred that the age of volcanism in the Nadi Kangri Formation is probably occurred between the Late Triassic Norian and Rhaetian, prior to the previous age-constraint of this Formation.

运用已有的生物地层资料确定肖茶卡组地层的沉积时间(晚三叠世诺利期-瑞替期)，从而推测那底岗日组火山岩形成时代略晚于这个时间，很可能早于前人关于该套地层的时代认识。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。
