文中详细地论述了新疆阿尔泰哈巴河一带古生代火山岩的地质、岩石化学、稀土元素地球化学特征。将其分为三个类型，认为火山岩是在陆缘裂陷槽的区域构造背景下发生和演化的。对各类型火山岩岩浆来源，上升模式也做了初步讨论。     

STUDY ON DEVELOPMENT STRATEGY OF SHIPPING CENTERS AND TRANSPORTATION NETWORKS IN THE YELLOW SEA RIM IN THE YELLOW SEA RIM

It is very important to establish cooperative mechanism to guarantee all members to develop their e-conomies in the Yellow Sea Rim. In this paper, the development strategies ofshipplng centers and transportation networkare discussed based on economic giobalization tendency. The results argue that a united transportation network should bebuilt in order to promote the economic competition of Northeast Asia in the world. As a key component of the economiccooperation, a hierarchical shipping centers network should be established with Hong Kong, Shanghai, Pusan, Koho,and Tokyo as cores. The authorities of China, Japan, R. O. Korea and D. P. B. Korea should make more efforts tobuild a set of cooperation institutions based on raising the transportation efficiency.     

SPECULATION ON DEVELOPING TOUR RESOURCES OF THE TOURNAMENT ATHLETICS IN HARBIN CITY

The exploitation and utilization of the tour resources of tournament athletics, including skiling, boat sail-ing, archery, ice engraving, snow engraving, has become a new trend of the development of Chinese tourism. Due tothe unique cold climate and superior geographic location, Harbin is a promising city for developing tour resources of tourna-ment athletics. Based on the analysis of the superiority and peculiarity of Harbin, the speculation on development of tour resources of tournament athletics in Harbin is proposed as follows : 1 ) Harbin should develop its special tour resources of tournament athletics associated with needs of market; 2) Harbin should take the advantages of rich resources and devel-op ice and snow entertainment in winter and travel for sight-seeing and spending summer;, 3) the adjustment of the layoutof ice and snow resources should be based on the idea of taking Harbin as the center and all-side opening at the largescale in the way of radiation; 4) tourism should be developed by the combined efforts of various departments to make feasi-ble plan, and the organizers should pay much attention to ensuring the safetv of tourists.     

湘西北地区铅锌矿床成矿规律及找矿方向

湘西北地区以盛产层控型低温热卤水铅锌矿床著称。矿床赋存于早寒武世晚期至早奥陶世早期分别受台地边缘相、台前斜坡相和局限台地相控制的碳酸盐地层中。矿体主要呈层状、似层状且具多层性,局部可切层,少数呈脉状。其产出受岩石的原生孔隙和容矿层内构造如虚脱—滑动空间、破碎带及裂隙系统等多因素控制。深大断裂带为主要导矿构造。容矿层不是矿源层,铅锌矿不存在同生沉积特征或痕迹。铅同位素年龄晚于赋矿地层年龄。矿质主要来源于碳酸盐建造以下的一大套碎屑岩建造,部分来自深部和造山带。矿床无围岩蚀变则无铅锌矿化,矿化富集强度与多类型围岩蚀变强度及层内构造空间发育程度呈正相关关系。该地区成矿地质条件优越,在划分出的4个找矿远景区内,许多低工作程度区和找矿空白区里仍具有巨大的找矿潜力,可望找到新的矿床。
