缅甸琥珀内含物的初步研究及其意义

琥珀是中生代白垩纪至新生代第三纪松柏科植物的树脂经地质作用而形成的有机混合物.目前世界上琥珀产地主要有欧洲波罗的海沿岸国家,中美洲的多米尼加、墨西哥,亚洲中国抚顺、缅甸、日本久慈和盘城、泰国,大洋洲澳大利亚、新西兰哈密尔顿等.然而,具有商业价值的白垩纪琥珀目前只有缅甸产出.缅甸琥珀资源主要分布于缅甸克钦邦密支那到德乃(Tanai)一带的胡康盆地.本研究在缅甸琥珀中观察和发现共20只生物个体,属15种生物,均属于节肢动物门.其中大部分属于昆虫纲,包含了膜翅目的蜂科、双翅目的蚊科等,另有一些未确切鉴定的种类.

A preliminary study of inclusions in the burmite (Myanmar amber) and their significance

Amber is a kind of organic substance made of pine resin formed by the geological process in Mesozoic Cretaceous-Cenozoic Tertiary strata. Currently, there are many amber localities all over the world, such as countries along the Baltic Sea, Mexico, Dominican Republic,Fushun in China, Kuji and Iwaki in Japan, Thailand, Australia, and New Zealand. However, the burmite from Myanmar is the only Cretaceous amber with commercial value. The principal resource of burmite is in the Hukawng Valley, which is situated between Myithyina and Tanai in Kachin State. In this study, LEICA M125 stereoscopic microscope of China University of Geosciences (Beijing) and LEICA EZ4D microscope (equipped with camera) of Insect Research Laboratory in Beijing Forestry University were used to observe the inclusions of the burmite sample. About 20 inclusions were observed, which belong to 15 species of Arthropoda. Most of them belong to insecta, like the Tenthredinidae of Hymenoptera and the Tipulidae of Diplura. However, some species remain undetermined.
