Exhumation history of the Higher Himalayan Crystalline along Dhauliganga-Goriganga river valleys, NW India: new constraints from fission track analysis [PDF]

open access: yes, 2009
New apatite and zircon fission track data collected from two transects along the Dhauliganga and Goriganga rivers in the NW Himalaya document exhumation of the Higher Himalayan Crystalline units. Despite sharing the same structural configuration and rock

Evidence for subsidence rate variation in the Newark Basin and its influence on the deposition of fluvial sediments of the Stockton Formation

open access: yesThe Depositional Record, EarlyView.
The Newark Basin has seen renewed interest recently as a potential location for carbon sequestration. This study uses a recently exposed outcrop to investigate the reasons behind varying lithologies and post‐depositional soft‐sediment deformation in the fluvial sandstones of the Stockton Formation. Using field observations and sediment geochemistry, we

Carbon cycling and interior evolution of water-covered plate tectonics and stagnant lid planets [PDF]

open access: yesA&A 627, A48 (2019), 2019
Aims: The long-term carbon cycle for planets with a surface entirely covered by oceans works differently from that of the present-day Earth because inefficient erosion leads to a strong dependence of the weathering rate on the rate of volcanism. In this paper, we investigate the long-term carbon cycle for these planets throughout their evolution ...

Tectonics of the Indonesian region

open access: yes, 1973
The plate-tectonic evolution of a region can be deduced by following the as­ sumptions that subduction zones are characterized by ophiolite, melange, wildflysch, and blueschist, that intermediate and silicic calc-alkaline igneous rocks form above Benioff

Accretionary Tectonics of the North American Cordillera [PDF]

open access: yes, 1983
Continental geology stands on the threshold of a change that is likely to be as fundamental as plate-tectonic theory was for marine geology. Ongoing seismic-reflection investigations into the deep crustal structure of North America are verifying that ...

Interglacial dust, ocean fertilisation and Neoproterozoic earth oxygenation

open access: yesThe Depositional Record, EarlyView.
Mineral dust is an integral part of modern ocean nutrient supply. It is originated mainly in deserts and by glacial processes. Given the global scale of the Neoproterozoic glaciations, we suggest that mineral dust formed during snowball events were blown to oceans, sustaining life, promoting CO2 sequestration and contributing to the oxygenation of ...

LEVHA TEKTONİĞİ NE ZAMAN BAŞLADI? KOMATİYİTLERİN VE MgO İÇERİKLERİNİN DEĞİŞKENLİĞİNE GÖRE LEVHA TEKTONİĞİ’NİN BAŞLANGICI

open access: yesBulletin of the Mineral Research and Exploration, 2017
Yerbilimcilerin en çok merak ettiği konulardan biri İlksel Dünya’nın (Early Earth) ne gibi evrimsel süreçler geçirerek günümüze ulaştığıdır. Bu süreçler içerisinde ise levha tektoniğinin ne zaman başladığı ayrı bir araştırma konusudur.
