| 摘 要： | 矿床形成后的变化与保存是矿床学研究与找矿勘探中一项极其重要但仍需进一步加强的基础性工作。影响矿床变化与保存的众多因素中，区域隆升与剥蚀是最为关键的因素之一。裂变径迹法是研究区域隆升与剥蚀的一种有效手段，它能为我们提供剥蚀速率以及剥蚀量的定量数据。一些产于花岗质岩体内与岩体有成因联系的矿床，其成矿深度可以通过详细的流体包裹体研究来获得。通过成矿深度与岩体剥蚀深度对比分析，能使我们更好地了解矿床形成后变化保存条件。裂变径迹法与流体包裹体研究相结合是矿床形成后变化与保存研究一种切实可行的方法。

| Abstract: | Post ore change and preservation, an aspect should be pay more attention, is a basic problem both to ore deposit geology and to mineral exploration. Regional uplift and denudation is the most important factors affecting post ore change and preservation of ore deposits. While fission track method is an effective way to study regional uplift and denudation, it can provide us denudation rate and degree quantitatively. Taking some ore deposits closely related to granitic intrusions as examples, ore forming depth can be calculated through fluid inclusion study. Thus comparison between ore forming depth and post ore denudation will led better understand of post ore change and preservation of ore deposits. Fission track method combining with fluid inclusion study will be a practical approach to post ore change and preservation in the study of ore deposit geology. |
