Rocks at asteroid impact site record first day of dinosaur extinction（图）
Rocks asteroid impact site record first day dinosaur extinction
2019/10/18
When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which cause...
Raised marine terraces in the Northern Calabrian Arc (Southern Italy): a ~ 600 kyr-long geological record of regional uplift
Calabrian Arc marine terrace uplift Pleistocene active fault
2015/9/15
The Sibari Plain in the Northeastern Calabrian Arc displays a well-developed suite of marine terraces. This paper
deals with i) the identification and correlation of the terraces; ii) their age assig...
A 3000-year record of surface-rupturing earthquakes at Günalan: variable fault-rupture lengths along the 1939 Erzincan earthquake-rupture segment of the North Anatolian Fault, Turk
paleoseismology North Anatolian Fault fault segment
2015/8/26
The North Anatolian Fault is a ca. 1200-km-long, right-lateral, strike-slip fault that forms the northern boundary of the Anatolian plate. A damaging sequence of earthquakes ruptured almost the entire...
Paleoseismic record obtained by coring a sag-pond along the North Anatolian Fault (Turkey)
Paleoseismology seismites sedimentary cores North Anatolian Fault
2015/8/26
Shallow lakes along minor structural bends or discontinuities of strike-slip faults are not usually paleoseismological target sites. In the present study, we show that a 2-m-deep, 700-m-long lake that...
Record of Early Toarcian carbon cycle perturbations in a nearshore environment: the Bascharage section (easternmost Paris Basin)
Black shale deposit early Jurassic the negative carbon isotope
2015/1/6
In order to understand the significance of the worldwide deposition of black shale facies in the Early Toarcian (~ 183 Ma), considerable attention has been drawn to this Early Jurassic sub-stage over ...
An open ocean record of the Toarcian oceanic anoxic event
ocean record Toarcian oceanic anoxic event
2014/12/31
Oceanic anoxic events were time intervals in the Mesozoic characterized by widespread distribution of marine organic matter-rich sediments (black shales) and significant perturbations in the global ca...
Quantitative bounds on morphodynamics and implications for reading the sedimentary record
Quantitative bounds on morphodynamics implications for reading sedimentary record
2014/4/8
Sedimentary rocks are the archives of environmental conditions and ancient planetary surface processes that led to their formation. Reconstructions of Earth’s past surface behaviour from the physical ...
Neogene uplift of the Tian Shan Mountains observed in the magnetic record of the Jingou River section (northwest China)
Neogene uplift Tian Shan Mountains observed in the magnetic record the Jingou River section
2014/4/15
The Tian Shan Mountains constitute central Asia’s longest and highest mountain range. Understanding their Cenozoic uplift history thus bears on mountain building processes in general, and on how defor...
Stable isotope compositions of a late Jurassic ammonite shell: a record of seasonal surface water temperatures in the southern hemisphere?
Stable isotope compositions late Jurassic ammonite shell seasonal surface water temperatures
2010/9/28
Exceptional preservation of aragonite secreted by ammonites offers an opportunity to determine the seasonal temperature variations of Mesozoic surface waters. Ontogenetic profiles of carbon and oxygen...
