Based on plentiful isotopic dating data and geological studies, the authors, in this paper, discuss the geological meanings of the two isotopic ages given by Lapierre et al., and conclude:① Mesozoic volcanic activities in Zhejiang are most frequent in 130～83 Ma, that is, from the early to late Cretaceous but not the late Jurassic;② The Jiande and Moshishan groups are nearly in the same period and not in an upper—lower stratigraphic relationship with each other;③ The period of 110～100 Ma is a transitional stage from the early high-K calc-alkaline dacite—rhyolite associated with diorite—granodiorite） to the late basalt—rhyolite（associated with K-feldspar granite—alkali granite）.

本文就Lapierre等文中124 Ma和97 Ma两个年龄的地质意义、幕次划分以及浙西与浙东火山岩时代对比作出评论，并厘定浙江中生代火山岩时代归属，提出：①浙江中生代火山活动时代为132～83 Ma；②浙西建德群与浙东磨石山群火山岩并不存在上下关系，地质接触关系、古生物组合和大量同位素定年数据都不支持Lapierre等的浙西与浙东火山活动幕次的对比方案；③ 110～100 Ma为早期高钾钙碱性英安岩—流纹岩（伴生闪长岩—花岗闪长岩）向晚期玄武岩—流纹岩（伴生钾长花岗岩—碱性花岗岩）过渡的转折期。

Early Cretaceous granitic volcanic-intrusive complex in Xiushanlinchang of northeastern Da Hinggan Mt. consists mainly of rhyolite, rhyolite ignimbrite-trachytic dacite, trachyandesite formed in eruptive cycle stage and adamellite porphyry-geode syenogranite-graphic alkali feldspar syenogranite formed in hypabyssal invasion stage.

大兴安岭东北部秀山林场一带的早白垩世花岗质火山－侵入杂岩体由喷发旋回期的流纹岩、流纹质熔结凝灰岩－粗面英安岩、粗安岩和浅成侵入期的二长花岗斑岩－晶洞正长花岗岩－文象碱长正长花岗岩构成。

By direct microscopic observations of thin section of Inada granite in the heating process, decrepitation temperature of fluid inclusions in quartz and feldspar was determined to be in a range from 170℃ to 550℃, and thermal microcracking due to the decrepitation of the fluid inclusions was ascertained.

通过常温及高温显微镜观察，查明了稻田花岗岩中流体包裹体的初始分布状态，并发现在高温条件下，由于流体包裹体的爆裂而导致花岗岩中微小裂纹的形成。

The main components of the Yonghe--Taibao granitic pluton are calc-alkali quartz diorite and monzonite.

永和太保花岗岩体主要为钙碱性石英闪长岩和二长花岗岩。

The change from granite to foliated granite is transitional and there is no discontinuity between them.

从花岗岩到片理化花岗岩的变化是逐渐过渡的，二者之间不存在不连续面。

It is shown in this research that:① The acoustic emission phenomena of rock discontinuously occur under the effect of temperature.

试验研究表明：①随着温度升高，岩石的声发射现象是间断发生的；②花岗岩存在一个开始发生热破裂的门槛值温度，其值为120 ℃左右；③试验温度范围内花岗岩热破裂的声发射现象可分为5个阶段，即岩石原生裂隙整合阶段、热破裂前声发射静默阶段、热破裂声发射阶段、大规模热破裂后声发射静默阶段、二次热破裂开始阶段。

The uplifting belt is composed of metasandstone, marble, overlying thick stromatolite (Jinyanshan Group of Jixian System). Metamorphic rocks of 450Ma± occur in both south and north active margin. Post-collision bimodal volcanic rocks and A-type granite occur in the middle and the north side;(4) Apa-Mangya tectonic melange belt consists of ophiolite (including ultramafic rocks, gabbro, plagiogranite and basalt) and flysch and eclogite of late Ordovician.

隆起带为中元古界变砂岩、大理岩，上覆厚层叠层石灰岩，南北边缘有均为450Ma左右的变质岩，中部和北侧分布有碰撞后双峰式火山岩与碱性花岗岩；④阿帕—茫崖构造混杂岩带，由超镁铁质岩、辉长岩、斜长花岗岩、玄武岩等蛇绿岩残片与晚奥陶世复理石沉积和榴辉岩块组成。

When meteorite hit the Earth surface, it created shockwave to transfer the kinetic energy to the Earth surface. When the speed of meteorite strike reached 10 km/second, the pressure of shockwave can reach several millions bar to compress the target terrane to produce heat, the effect of impact deformation caused by it is several scales stronger than rock intensity, the granite would melt down once the pressure of shockwave reached about 500 thousands bar, the granite would gasify (solid became liquid and meanwhile further became gaseity) once reaching over 600 thousand bar.

当陨石撞击地表时产生冲击波把陨石的动能传给地表，在陨击速度达到10公里/秒时冲击波的压力可达到数百万巴并压缩靶点岩层物质产生热，它产生的冲击变形效应比岩石强度大几个量级，冲击波压力约50万巴时花岗岩就熔化，大于60万巴时花岗岩就气化（在固态转为液态同时进一步转为气态）。

An evolutionary sequence of paleoproterzoic granite in the Luliang area was initially established based on a large number of isotopic geochronology data and geologic settings of each-stage granites were determined on the basis of geochemical features and geologic characteristics.

根据大量同位素年代资料，初步建立了吕梁地区古元古代花岗岩的演化序列，并根据地球化学特征和综合地质特征确定了各期花岗岩形成的地质背景。
