Extensive flows of the Columbia River Basalt (CRB) Group in Washington, Oregon, and Idaho are dominantly inflated compound pahoehoe sheet lavas. Early studies recognized that CRB lavas flows, with textures suggesting low flow velocities, but it was thought great thickness extent major required very rapid emplacement as turbulent floods lava over a period days or weeks. However, small volume (< 1 km³) on Kilauea, Hawai'i, demonstrate such can thicken by at least an order magnitude through...

To investigate the distribution of microbial biomass and activities to gain insights into physical controls on activity potential long‐term survival in subsurface, 24 shale sandstone cores were collected from a site northwestern New Mexico. Bacterial core samples ranged below detection 31.9 pmol total phospholipid fatty acid (PLFA) g‐1 rock with no apparent relationship between lithology PLFA abundance. No metabolic activities, as determined by anaerobic mineralization [14C]acetate...

The synthesis of 3D facial animations from speech has garnered considerable attention. Due to the scarcity high-quality 4D data and well-annotated abundant multi-modality labels, previous methods often suffer limited realism a lack flexible conditioning. We address this challenge through trilogy. first introduce Generalized Neural Parametric Facial Asset (GNPFA), an efficient variational auto-encoder mapping geometry images highly generalized expression latent space, decoupling expressions...

To understand the conditions under which microorganisms exist in deep hydrocarbon reservoirs, sidewall cores were collected from a natural gas‐bearing formation, 2800 m below surface Taylorsville Basin, Virginia. Data chemical and microbial tracers controls indicate that interiors of some contained indigenous to rock formation. The cultured composed primarily saline‐tolerant, thermophilic fermenting, Fe(III)‐reducing, sulfate‐reducing bacteria (1 104 cells/g). physiological capabilities are...

Cores were collected from Late Cretaceous and Early Tertiary rocks in the Piceance Basin of western Colorado, USA, to investigate origins subsurface microorganisms under geological conditions likely constrain microbial transport survival. The sampled strata 856–862, 1996–1997 2091–2096 m recorded peak paleotemperatures 120–145°C 40–5 million years ago, while present temperatures range 43 85°C. analyzed for culturable anaerobic bacteria (Fe(III)- Mn(IV)-reducing bacteria, fermenters, sulfate...

ABSTRACT As high‐grade potash resources become increasingly scarce and lithium is recognised as a valuable co‐product, the low‐grade solid deposits in Mahai Salt Lake, Qaidam Basin, have significant targets for resource development. However, inefficient release of potassium from these ores constrains their economic feasibility industrial use. This study addresses this challenge by employing x‐ray diffraction (XRD), scanning electron microscopy coupled with energy dispersive spectroscopy...

The Salt Lake Mahai in Qaidam Basin, western China contains large and thick lithium-rich clay sediments that exhibit great economic potential for lithium exploration. This study analyzed the occurrence of related dissolution mechanisms these through mineral identification, chemical analyses, monitoring brine composition evolution. Our results show mainly occurred as interbeds between salt layers fillings crystals. dominant is illite, followed by chlorite, kaolinite, an illite-smectite mixed...

Hairstyles are intricate and culturally significant with various geometries, textures, structures. Existing text or image-guided generation methods fail to handle the richness complexity of diverse styles. We present TANGLED, a novel approach for 3D hair strand that accommodates image inputs across styles, viewpoints, quantities input views. TANGLED employs three-step pipeline. First, our MultiHair Dataset provides 457 hairstyles annotated 74 attributes, emphasizing complex styles improve...

Abstract. The International Continental Scientific Drilling Program (ICDP) has long espoused studies of deep subsurface life, and targeted fundamental questions regarding including the following: "(1) What is extent diversity microbial life what are factors limiting it? (2) types metabolism/carbon/energy sources rates activity? (3) How adapted to conditions? (4) do communities affect energy resources? And (5) how does biosphere interact with geosphere atmosphere?" (Horsfield et al., 2014)...
