In northeast Taiwan, many areas are affected by various tectonic forcings. Some areas appear to have a subsidence tendency, whereas others reflect uplift activities on the surface, due to tectonic northward compressive forcing growth and decline. Owing to the presence of widespread mountain areas, limited geodetic surveys in the field have made dat...

Numerical groundwater flow simulation involves manual and tedious pre-processing and post-processing procedures. Hence, this study developed a systematic and efficient workflow to alleviate model buildup and data-processing burdens, allowing researchers to focus on the application aspects of simulation results. This highly automatic workflow allows...

Lichens are abundant with functional groups that are capable of adsorbing dissolved metals in moisture and intercepting suspended particles in the atmosphere. Using lichen chemistry as an indicator is a prominent method of assessing a long-term baseline of atmospheric quality. This study collected foliose lichens, Parmelia sp., from an area with in...

A new downhole sampler, GTFSampler, is designed to collect in-situ geothermal fluids and preserve the conditions of the sampling depth. The GTFSampler is mainly composed of a stainless sampling cylinder and a gas driven shut-in valve, which are hosted in an equipment protector. The sampler assembly connects to a stainless tube for hoisting in a bor...

During seismic slip, the elastic strain energy released by the wall rocks drives grain fragmentation and flash heating in the slipping zone, resulting in formation of (nano)powders and melt droplets, which lower the fault resistance. With progressive seismic slip, the frictional melt covers the slip surface and behaves as a lubricant reducing the c...

Miocene lenticular basaltic volcanics that have mineral-trapping capability enclosed in the potential sandstone reservoirs in Northwestern Taiwan inspired a CO2 multi-sequestration shale-sandstone-basalt system. To analyze the behavior of injected CO2 and the mineral trapping capability in the proposed multi-sequestration shale-sandstone-basalt sys...

Heavy metal contamination commonly appears in mining areas and volcanic watersheds due to the acidic drainage water. Under the hydrochemical condition, the solar photocycle would result in changes of the water temperature, in photosynthesis and in iron photoreduction, which leads to substantial hydrochemical fluctuations, especially for heavy metal...

The Hoping power plant (HPP), located on the northeastern coast of Taiwan, is considered an ideal site to test the accelerated weathering of limestone (AWL) technique for fossil fuel CO2 mitigation because the required reactants, seawater and limestone, are readily available and inexpensive to obtain. In this study, we investigated the current stat...

a b s t r a c t A million-ton-scale CO 2 geological storage project was planned by the Taiwan Power Company in the Taiwan Basin. The site, half on-shore and half off-shore, has a regional shale formation underlain by two sandy saline aquifers. Numerical models were used to comprehensively assess CO 2 geological storage including the CO 2 plume evol...

The Darongshan granitic suite (~10,000km2) consists of five major units (Taima, Nadong and Jiuzhou plutons, and Pubei and Darongshan batholiths) typical of peraluminous S-type granitoids containing abundant granulite inclusions in the Cathaysia block, South China. Six samples from these plutons and batholiths have been investigated using both LA-IC...

a b s t r a c t Huayu, the only non-basalt islet in the Penghu Islands, consists mainly of andesite lavas intruded by some intermediate (dacite/granodiorite) and felsic (rhyolite/granite) dikes. The LA-ICPMS U–Pb zircon age determination yields 437 ± 13 Ma (n = 16, MSWD = 6.9) for the andesite lava and 63.3 ± 1.5 Ma (n = 7; MSWD = 2.9) for its pota...

Cretaceous Late Yanshanian (LY) magmatism produced large amounts of I-type granitoids in the Southeast Coast Magmatic Belt (SCMB). I-type granitoids from Xiaojiang-Liangnong complexes (N Zhejiang) in the northern part of this belt are characterized by containing abundant mafic microgranular enclaves (MMEs). On the basis of petrography and mineralog...

The widespread Mesozoic granitoids in South China ($135,300 km 2) were emplaced in three main periods: Triassic (16% of the total surface area of Mesozoic granitoids), Jurassic (47%), and Cretaceous (37%). Though much study has been conducted on the most abun-dant Jurassic Nanling Mountains (NLM) granites, their rock affinities relative to the Tria...

Rhyolite-dominating bimodal volcanic suites (rhyolite/basalt), mafic dikes and A-type granites distribute from N Zhejiang to S Fujian over 800 km in the Southeast Coast Magmatic Belt (SCMB) – the Late Yanshanian (LY) orogenic belt in SE China. Data of 40Ar/39Ar and K–Ar whole-rock ages and LA-ICPMS U–Pb zircon ages indicate that rhyolitic volcanism...
