Papers: Global Tectonics, Cryogenian Period, Himalaya Miocene LakesI've come across quite a few interesting papers on diverse topics in the past couple of weeks. Most of them are 'big question' themes, dealing with processes taking place on global scales. Here are the links.
1) Subduction Initiation of the Wilson Cycle - In plate tectonics, the Wilson Cycle refers to cyclical ( frequency of 100's of millions of years) breakup of continents and the opening and closing of ocean basins. But how is subduction initiated and new convergent plate boundaries formed? Some good examples from the Western Pacific margin and eastern Indonesia.
2) How Subduction Broke Up Pangaea - Was it top down forces.. i.e. the pull exerted by subducting slabs or was it the horizontal traction exerted by a convecting mantle (bottom up) that broke up the supercontinent?
3) Why is Africa Rifting? - Insights into the formation of the famous East Africa rift system.
4) Gondwana Large Igneous Provinces: distribution, diversity and significance - Synopsis of several papers that explore the link between prolonged magmatic episodes, tectonics, climate shifts and sedimentation patterns in Gondwana continents.
1) Snowball Earth climate dynamics and Cryogenian geology-geobiology - In the Cryogenian Period, between around 715 to 635 million years ago, the earth was blanketed in two prolonged glaciations. Before these glaciations, the earth was a microbial planet. The end of these glaciations is associated with the evolution of multicellular complex life. What were the conditions during the Cryogenian Period that influenced the evolution of life?
1) Oligocene‐Miocene Great Lakes in the India‐Asia Collision Zone - Mount Kailash is an important pilgrimage site for Hindus. The sediments that make up this mountain were deposited in narrow basins in the India-Asia collision zone. They preserve a record of surface environments and geodynamic mechanisms operating within the suture zone during the convergence of India with Asia.
