"本研究累積近五年來在屏東中央山脈地區幾條河流橫切之地質剖面(跨越成岩 至淺變質帶)的野外調查成果，探討區內發現數量豐富且分佈廣泛之各種纖維狀 組織石英脈的成因。其內常見發育形態良好的石英晶體，而這類晶體因保有裂隙 開裂時期等時發育的原生纖維狀組織及帶有特殊的流體包裹體序列特徵。此特徵 被認為內部具有等構造時期所封存之原生及假次生型流體包裹體，而這些包裹體 有別於普通石英脈中常見受到多次洩漏及再結晶作用混合的次生型包裹體，具有 特定時期及環境的代表性。經由彙整前人文獻及產地資訊後得知，這類石英脈產 出主要出現於造山帶地區，著名產地如: 歐洲阿爾卑斯山山脈、亞洲喜瑪拉雅山 山脈、北非的亞特拉斯山山脈...等地。相關研究及記錄最早則為歐洲各國學者 所提出，以探討各種石英脈組織內礦物發育理論模型與構造的關係。最後用於探 討歐洲阿爾卑斯山山脈在末次大陸碰撞時期地體構造演變的區域性研究。研究規 劃藉由屏東中央山脈之特定地質剖面中所發現的石英標本，針對內部富含的原生 及假次生型流體包裹體做成分定性定量分析，以及均化溫度和冷凍溫度分析。並 針對其共生礦物進行同位素與定年分析。配合區域構造地質及石英脈發育模型來 探討造山作用末期，地下流體特性與區域構造的演變。" "This study accumulated the results of 5-year field investigations from the south west Central Mountain Range in Pingtung (across the diagenetic to anchi zone region ) to research the plentiful and widespread fibrous quartz veins. Many well formed fibrous quartz specimens have the Fluid Inclusions Assemblage (FIA), which composed of the primary and pseudo-secondary fluid inclusions in the crystals. This FIA feature is considered as isostructure stage during quartz growing, and is different from those second inclusions with healing and recrystallization after quartz growth. The fluid inclusions can verify a special event and environment. By comparing with the previous studies and the information of the occurrences, they show that this kind of quartz vein grew in the uplifting mountain ranges. The famous localities like the Alps mountain range in Europe, the Himalaya mountain range in Asia and the Atlas mountain range in the northern Africa...etc. Some of the most earlier and important research has been published by the European specialists. They investigated the fibrous quartz veins and figured out the crystal growth model related to the development of structure. Finally, some research used this method to model the last continental collision history across the Alps mountain ranges. This research will focus on the primary and secondary fluid inclusions of the quartz occurring in the Central Mountain Range, Pingtung. To quantify and determine the homogenous and freezing temperatures of the fluid inclusions in quartz. Then, we will analyze the isotope data and age dating of the intergrowth minerals . After integrating the regional structure features and the developed model of quartz vein, we can discuss the regional fluids and tectonic evolutions during the last mountain building stage."
