... HE magnetotelluric (MT) sounding offers significant advantages in terms of large detection depth and simplified survey deployment, making it widely applied in resource exploration and deep electrical structure imaging [1], [2], [3], [4], [5]. However, natural MT signals collected on the surface of the earth are weak, making it highly susceptible to various anthropogenic noises. ...

... Petrified wood, which accounts for 80% of the biomass of the entire plant body (Martín-Closas and Gomez, 2004;Philippe et al., 2009;Wang et al., 2017), is crucial for exploring the compositional characteristics of flora and the evolutionary history of vegetation (Peralta-Medina and Falcon-Lang 2012). Cretaceous petrified wood is pretty abundant in China, with the majority documented in Northeast China (e.g., Zheng et al., 2008;Yang et al., 2013;Ding et al., 2016;Wang et al., 2017;Tian et al., 2018Tian et al., , 2020Cheng et al., 2023). The Huolinhe Formation is an important horizon for the Early Cretaceous flora in Northeast China with diverse and abundant twodimensionally preserved fossil leaves (Deng, 1991(Deng, , 1995Xu et al., 2013Xu et al., , 2015Xu et al., , 2017Guignard et al., 2019;Dong et al., 2020); however, three-dimensionally preserved wood fossils with anatomical details are relatively rare with only a few records (Cui, 1995;He, 1995;Ding et al., 2000). ...
