dc.description.abstract | Taiwan orogeny eroded sediments then transported to adjacent basins. The eroded materials contain not only detrital from inorganic rocks but also organic matters. After the sediments being deposited in basin, organic matters prone to bio-degradation and coalification through burial time, and preserve the basin burial history. Transformation of clay mineral is another technique to observe basin burial history. Although there are many thermal burial history studies in western Taiwan because of the evaluation petroleum potential, however Coastal Range of eastern Taiwan is comparingly less studied. So, it served as a good candidate to observe the thermal burial history. This study collected sedimentary rocks and coalified woods from north to south with Shuilien, Fengpin, Chimei, Loho, Sanshien, and Madagida sections. We used the coalified woods and separated organic matters from sedimentary rocks and made into pellets to measure their vitrinite reflectance (Ro%). Furthermore, Rock- Eval pyrolysis was applied to acquire the Tmax, a parameter for maturity evaluation. Additionally, X-ray Diffraction (XRD) and Short Wavelength Infrared (SWIR) techniques were used in this study. Ro% of Separated organic materials showed increase and highly disperse through younger upward of stratigraphic column, on the other hand, the coalified woods exhibited increase Ro with depth. Combined with Rock-Eval pyrolysis method, Madagida section showed some S1 peak higher than S2 peak, and Tmax lower than <400 ̊ C in Sanshien section. The result indicates organic matters from Fanshuliao Formation of Loho and Madagida sections belonged to early mature stage, with gas prone organic matters (Type III, IV). The upward increase of Ro% implied inclusion of the reworked detritus organic materials. On the other hand, clay mineralogy such as SWIR from Shuilien and Madagida sections, exhibited D1900nm decreased through burial depth of selected stratigraphic columns. Finally, Raman Spectrocopy Carbonaceous Materials (RSCM) was also used in this study, the results of the northern part Coastal Range had receveived relative higher metamorphic grade gravel sediments than southern part in 2Ma. However Chimei section in the central part of Coastal Range had received gravel sediments with metamorphic grade up to green schists facies. Compared with the reworked vitrinite reflectance results, Ro% constraint in 2-3.99 indicated six sections of Coastal Range received sediments with the Prehnite -Pumpellyite facies since 3.35Ma. | en_US |
