Combining geologic mapping and stratigraphic reconstruction of lava flows at Sapas, Maat and Ozza Montes, three potentially young volcanic structures of Atla Regio on Venus, with analysis of the spectral signature (radar emissivity anomalies) characterizing each mapped flow, Brossier et al. (2021, https://doi.org/10.1029/2020je006722), conclude that some of the lava flows at Maat Mons may be geologically recent (∼25 Ma) (Smrekar et al., 2010, https://doi.org/10.1126/science.1186785; D'Incecco et al., 2017, https://doi.org/10.1016/j.pss.2016.12.002; Zolotov, 2018, https://doi.org/10.1515/rmg.2018.84.10; Brossier et al., 2020, https://doi.org/10.1016/j.icarus.2020.113693, 2021, https://doi.org/10.1029/2020je006722). The lava flows of Sapas and Ozza Montes are consistent with weathered lava flows forming chlorapatite and some perovskite oxides. We discuss the reasons why, besides the importance of the results they obtained, the methodology they used can be very valuable for future investigations with higher resolution datasets.

地质监督光谱调查作为识别金星火山活动区的关键方法

Brossier 等人，结合对金星上阿特拉区的三个潜在年轻火山结构 Sapas、Maat 和 Ozza Montes 熔岩流的地质测绘和地层重建，以及对表征每个测绘流的光谱特征（雷达发射率异常）的分析。（2021 年，https://doi.org/10.1029/2020je006722）得出结论，Maat Mons 的一些熔岩流可能是地质上最近的（~25 Ma）（Smrekar 等人，2010 年，https://doi.org /10.1126/science.11​​86785；D'Incecco 等人，2017，https://doi.org/10.1016/j.pss.2016.12.002；Zolotov，2018，https://doi.org/10.1515/rmg. 2018.84.10；Brossier 等人，2020，https://doi.org/10.1016/j.icarus.2020.113693，2021，https://doi.org/10.1029/2020je006722）。Sapas 和 Ozza Montes 的熔岩流与形成氯磷灰石和一些钙钛矿氧化物的风化熔岩流一致。
