As blueschists are thought to be formed in subduction zones, the absence of Precambrian blueschists has been adduced as evidence that plate tectonics did not operate on the early Earth. Although this conclusion is not inevitable, in that ancient mobile belts are more likely to have been ...
To obtain this ideal, we may subconsciously reject evidence that conflicts with the hypothesis, while overemphasizing evidence that supports it. We must beware this subconscious theory-based rejection of data.Children and adults use similar strategies to cope with evidence that is inconsistent with ...
3.2 billion years ago, interpreted to indicate the start of global-scale plate tectonics no later than that time. Methods We compiled a database of basaltic rocks (n = 3,127) and komatiites (n = 2,740) for major and trace elements (including rare earth elements) mainly using ...
It supports a concept that such giant melt sheets, as 50 km thick and the 2500 km in diameter South Pole-Aitken11, were able to undergo large-scale igneous differ- entiation and may, therefore, have contributed to the diversifi- cation of melt lithologies in the Moon's early crust. In...
The state of Virginia erected a memorial to him that cites this passage. Isaiah 40:22 Some have claimed that the Bible supports the “flat earth theory.” But this passage declares that God sits upon the “circle of the earth.” (See also the mention in Proverbs 8:27 of a compass or...
The diverse geometries and kinematics of the tearing earthquakes indicate that upper lithosphere tearing in this region is likely accommodated by multiple faults rather than a single through-going structure. The intersection of the compact regions of maximum slip for the 2014 fault planes supports this...
This vegetation pattern is typical to what is found around the Bay of Bengal today and supports a monsoon-like climate at the time of the Yaw Formation. Bioclimatic analysis further suggests that in the late Eocene, the Yaw Formation was more seasonal, drier, and cooler compared to modern-...
Crustal and lithospheric structure in the Eastern Indian Shield (EIS), where the oldest Hadean rocks of 4.0–4.2 Ga11,12 were found, have been investigated using various seismic techniques, suggesting that vertical tectonics (plume activities) controlled the Neo-Archean crustal accretion at the Singh...
A recent S receiver function study indicates lithospheric thinning in Southern China52, which supports the delamination model for this area53,54. Therefore, we consider that the lower crust/lithosphere delamination55 beneath the Cathaysia Block might have led to lithospheric thinning in this area and...
(iii) Groves and Santosh (2016) argue that the only realistic source of fluids and gold is a subducted oceanic plate and its overlying sulfide-rich sedimentary package, or associated mantle wedge. (iv) Deng et al. (2020) considered a metasomatic and fertile lithospheric mantle resulting from ...
