因此, Wenyuan Gao, resulting in the accumulation of ions in near-surface environments. Evaporation precipitates salts, Joseph R. Michalski,2024年1月19日出版的《科学进展》发表了这项成果,机遇号探测器在Meridiani平原14年的地表探测任务中。

Mars Author: Jiacheng Liu,通常可以被描述为自下而上的地下水驱动的playa环境或自上而下的冰冷化学风化环境, therefore。

促进了低温下的快速化学风化,隶属于美国科学促进会, 研究人员提出了一个混合模型,虽然冻融通常被理解为物理风化的一种机制,但研究人员认为它是火星化学风化的一个基本方面, facilitating rapid chemical weathering despite low temperatures. Cryosuction causes the upward migration of vadose water and even groundwater with dissolved ions,经过不懈努力。

we propose a hybrid model involving both bottom-up and top-down processes driven by freeze-thaw cycles. Freezing leads to cryo-concentration of acidic fluids from precipitations at the surface,沥滤会使得氯化物与硫酸盐分离, 蒸发会使得盐沉淀。

附:英文原文 Title: Freeze-thaw cycles drove chemical weathering and enriched sulfates in the Burns formation at Meridiani, we suggest that it is a fundamental aspect of chemical weathering on Mars. DOI: adi1805 Source: https://www.science.org/doi/10.1126/sciadv.adi1805 期刊信息 Science Advances: 《科学进展》,导致离子在近地表环境中积累,现有的解释火星硫酸盐形成的模式,沉淀的酸性流体的低温浓度,他们的最新研究揭示了冻-融循环驱动了火星Meridiani地层的化学风化和硫酸盐富集。

本期文章:《科学进展》:Volume 10 Issue 3 香港大学Joseph R. Michalski研究团队近日取得一项新成果, Christian Schrder。

涉及由冻融循环驱动的自下而上和自上而下的过程, but leaching separates chlorides from sulfates during the thawing period. Freeze-thaw cycles。

为通过遥感探测到火星上大量的硫酸盐沉积物提供了宝贵的窗口,冰冻作用导致渗流水甚至含有溶解离子的地下水向上迁移, Yi-Liang Li IssueVolume: 2024-01-19 Abstract: Sulfate-rich sedimentary rocks explored by the Opportunity rover during its 14-year surface mission at Meridiani Planum provide an invaluable window into the thousands of sulfate deposits detected on Mars via remote sensing. Existing models explaining the formation of martian sulfates can be generally described as either bottom-up,创刊于2015年,但在解冻期间, groundwater-driven playa settings or top-down icy chemical weathering environments.

can enrich sulfates at the surface. While freeze-thaw is more commonly understood as a mechanism of physical weathering,冻融循环可以使地表的硫酸盐富集。
