計畫緣起

位處歐亞板塊與菲律賓海板塊邊界的台灣,乃是現今地球板塊活動最劇烈、頻繁的地區之一;台灣島開始形成至今只有六百多萬年、全島長度只有四百公里,卻是麻雀雖小五臟俱全,造山帶的各種特徵幾乎都有,展現地質地景的多元樣貌。

國立台灣大學地質科學系之多數館藏上承前台北帝大時代,資料量至為龐大多樣,深具資料保存、維護、研究、教育等功能。透過「國家典藏數位化計畫」,在專家協助與單位交流討論中,已經完成從編目、整理、資料之判讀,至標本建檔、拍攝等數位化工作、以及資料庫建置之其他相關作業,建置豐富的數位資料庫以永久保存,並提供大眾使用。

惟因個別地質標本在教育及研究使用上的侷限性易造成知識系統的零碎化,唯有透過野外實際產狀的描述與記錄,方可彰顯出台灣位處現今地球板塊活動最劇烈、頻繁地區之獨特價值,以出露於地表的岩石作為地質運動歷程解碼,揭露本地的地質生成史。同時進行各地地層的研究工作,確認其對比及排序,才能瞭解過去地球的氣候、地理環境、以及物種演化的進程,拼湊出地球過去的珍貴歷史。

Origin of Project

Taiwan is located at a site that straddles the contact zone between the Eurasian plate and the Philippine Sea plate. This site is one of the locations with the most frequent as well as most vigorous plate tectonic activities. The island of Taiwan is only 6 million years old since its formation, and yet even though the island is only just 400 km in length, it is replete with all of the characteristic features of mountain-building process, both in geological evidence as well as in geomorphologic features.

Archived rock collection in the Geosciences Department, National Taiwan University, for the most part, is legacy from the previous Taihoku Imperial University. The vast, variegated contents of this collection are worthy of safekeeping and maintaining for studying and educational purposes. Through the National Digital Archiving Project and under guidance from experts and scholars in various fields in geosciences, most of the works on cataloging, classifying, data interpretation, and also through communication exchanges and interactive dialogues and discussion with other establishments, filing of collected and archived items, photographing and digitizing, and data bank establishing have been completed. As a consequence, a rich, digitized data bank has been established for public use as well as attaining permanent archival preservation purpose.

However, limitation resulting from individual use of specimens in research or educational purposes often leads to fragmentation of the learning system, and only through faithful field recording and descriptions of actual occurrences of specimens can the unique value of the most vigorous, most active and most frequent of plate tectonic sites, such as where Taiwan is located, be best revealed; only through the use of rocks that crop out in the field can the geologic processes be truthfully and vividly decoded to reveal the growth history and development of the local geology. Researches on stratigraphy of the area and on the sequences of rock formations in the area are also conducted for the purpose of understanding the past climate, environment and evolution processes of various biotas. It is only by way of these can the pieces of the vast jigsaw puzzle of the past history of the earth be fitted together.
