一、绪论 最近十年来,在应用气液包裹体研究经济矿床方面已取得了巨大的进展。由于仪器方面的进展和对流体捕获以及重结晶的机理有了进一步的了解,因而包裹体研究已得到了普遍的承认而且全世界都正在广泛地用来解决矿床地质测温和地质测压问题。但是测定原生流体成分的问题仍未解决,这主要是由于缺少可用于单个包裹体测定的简便易行 I. INTRODUCTION In the recent decade, tremendous progress has been made in the study of economic deposits using gas-liquid inclusions. Due to the advances in instrumentation and understanding of the mechanism of fluid capture and recrystallization, inclusion studies have gained widespread recognition and the world is now widely used to solve geological and geothermal stress measurements. However, the problem of determining the composition of the primary fluid remains unresolved, mainly due to the lack of easy and easy-to-use
