Abstract:	本研究透過使用 Geoflac 和 DynEarthSol 進行數值模擬，探討臺灣雪山山脈與澳洲西北大陸棚羅巴克盆地的地質與熱演化。在雪山山脈的模擬中，Geoflac 結合熱年代學，重建因造山抬升所驅動的快速冷卻與剝蝕過程，捕捉了約 6-7 百萬年之間的短期熱歷史。相比之下，對於歷時近 2.9 億年的羅巴克盆地的分析則使用 DynEarthSol，顯示該沉積盆地因放射性產熱與逐步的地殼變薄而呈現長期的熱流特徵，對油氣成熟具有重要意涵。研究結果闡明了地質時間尺度如何塑造熱演化，顯示短期造山活動與長期裂谷階段各自導致不同的熱分佈模式。本研究確認在區域地質與熱歷史中，數值模擬在推進對構造過程的累積效應的洞見與價值。;This study investigates the geological and thermal evolution of the Hsuehshan Range in Taiwan and the Roebuck Basin on Northwest Shelf of Australia through advanced numerical modeling with Geoflac and DynEarthSol. In modeling the Hsuehshan Range, Geoflac incorporates thermochronology to reconstruct rapid cooling and exhumation processes driven by orogenic uplift, capturing the region’s short-term thermal history over approximately 6-7 Ma. In contrast, analysis of the Roebuck Basin, spanning nearly 290 Ma and conducted with DynEarthSol, reflects the long-term heat flux characteristic of sedimentary basins, shaped by radiogenic heat production and progressive crustal thinning with significant implications for hydrocarbon maturation. The findings elucidate how geological timescales shape thermal evolution, showing that short-term orogenic activity and extended rifting phases each result in distinct thermal patterns. This study affirms the value of numerical simulations in advancing insights into the cumulative effects of tectonic processes on regional geological and thermal histories.
