The Dabie Mountains are unique among ultrahigh pressure metamorphic terranes in having the most profound post collisional plutonism The Mesozoic shoshonitic and calc alkaline intrusive rocks can be divided into three groups with different isotopic ages, rock assemblages and chemical features Group I consists of late Triassic (~ 210 Ma) mafic monzodiorites It could have been generated by partial melting of enriched subcontinental lithosphere mantle due to slab breakoff Group II consists ma...

第 I组，主要由晚三叠世（约210 Ma）二长闪长岩辉长岩体组成，它可能是在板片断离过程中富集的大陆岩石圈地幔部分熔融的产物；第I I组，由中侏罗世－早白垩世（160～120 Ma）的角闪石英二长岩、黑云母二长花岗岩和正长花岗岩组成，主要是由幔源岩浆的分离结晶与地壳混染共同作用的产物；第II I组，以白垩纪（125～95 Ma）的花岗岩和花岗斑岩为代表，是在热穹窿作用过程中大别杂岩深熔作用和高度演化的产物。

The feature of earth chemistry of volcanic rock in Xiangshan Group reflects that it belongs to the series of oceanic tholeiite in oceanic spreading tectonic environment.

结果 香山群的时代划归为中晚寒武世较合适；香山群主体是一套由板岩、细、粉砂岩和砂岩组成的浊积岩系，其砂岩类型主要是长石石英砂岩、细粒石英砂岩和粉砂质石英砂岩，前寒武纪变沉积岩和花岗片麻岩为主要碎屑来源和物源区组成；砂岩的岩石地球化学特征指示香山群属发育在被动大陆边缘斜坡环境中的沉积物，火山岩岩石地球化学特征反映其应属大洋扩张构造环境下的大洋拉斑玄武岩系列。

Combined with the regional data the research indicates that (1) the Tianmenshan main body formed in the Middle Jurassic Epoch, whereas the minor body was the further differentiated and evolutive product of the main body;(2) in the Chongyi-Dayu-Shangyou ore concentrated area, the west of Gannan area, the diagenetic age and metallogenic age are basically concordant, and the mineralization concentrated during 150~155 Ma;(3) from the middle-plutonic granite intrusion to the hypabyssal granite-porphyry vein, the magmatic activities experienced only 1~5Ma, indicating there was the concentrated period of mineralization.

结合区域资料，研究表明：①天门山岩体的主体形成于中侏罗世，补体是主体进一步分异演化的产物；②在赣南西部的崇余犹矿集区内成岩与成矿的年龄基本上是协调一致的，成矿集中期为150～155 Ma；③岩浆活动由中深成相花岗岩侵入体演化到浅成相花岗斑岩脉仅相差1～5Ma，表明存在成矿集中期。

The major dominant species of predatory enemies were Erigonidium graminicola and Theridion octomaculatum and their individuals were 81.4 percent of the total predatory enemy individuals of the community.1.2 Spatial patterns and their dynamics of major dominant predatory enemies ofarthropod communityThe research results showed that Pieris rapae distributed mainly on heart leaves and back of inner leaves of cabbage plants, Plutella xylostella distributed mainly on the back of cabbage leaves and Lipaphis erysimi distributed widely in cabbage plants. Among the major dominant species of predatory enemies, Sitticus sinensis distributed mainly on the front of leaves of cabbage plants in spring cabbage fields, and Misumenopos tricuspidata and Propylaea japonica distributed widely in cabbage plants.

在捕食性天敌中蜘蛛10种，捕食性昆虫3种，主要优势种为草间小黑蛛、八斑球腹蛛，其数量占捕食性天敌总数量的81.4%。1.2节肢动物群落主要优势种的空间格局及其动态研究结果表明，害虫优势种菜青虫主要分布于甘蓝心叶和甘蓝叶反面，小菜蛾主要集中分布在甘蓝叶的反面，而菜蚜在甘蓝植株内的分布较广；春甘蓝田捕食性天敌优势种中华跃蛛在外层叶正面分布较集中，三突花蛛与瓢虫类在甘蓝植株内的分布较广。
