Western Pacific plate subduction played a key role in the late Mesozoic geologic evolution and volcanism in East Asia. New and published zircon U–Pb ages of extrusive rocks are compiled in SE China. Results show that the volcanism mainly spanned ~95 Myr (mainly 70 Myr, Late Jurassic–Early Cretaceous) and migrated northwest from the coast inland, implying the Paleo-Pacific Plate subducted northwestward and the roll-back subduction did not begin until the Aptian (~125 Ma) of the mid-Cretaceous.

We have discovered a new way of measuring the three-dimensional distribution of radioactive elements in individual crystals by shining a very bright light on apatite crystals at the Advanced Photon Source at Argonne National Laboratory. This allows us to learn about the rates and timing of geologic processes and to help resolve problems that previously were unsolvable because we had no way to make this type of measurement.

We present an approach to U-Pb dating of carbonates using isotopic image maps. The maps are divided into squares called virtual spots. For each virtual spot, statistical values (mean, uncertainty) are used to determine the age. The user can modify the size and location of the virtual spots and select those that give the most robust age. This approach, applied to high spatial resolution images, makes it possible for the first time to obtain satisfactory ages on images as small as 100 µm x 100 µm.

Short summary
Growth of microorganisms in the Southern Ocean is limited by low iron levels. Iron delivered from beneath the Antarctic Ice Sheet is one agent that fertilizes these ecosystems, but it is unclear how this nutrient source changes through time. Here, we measured the age and chemistry of a rock that records the iron concentration of Antarctic basal water. We show that increased dissolution of iron from rocks below the ice sheet can substantially enhance iron discharge during cold climate periods.

We characterize three natural carbonate samples with elevated uranium/lead (U/Pb) ratios to demonstrate techniques improving the understanding of U incorporation in carbonates for U/Pb dating. With the rapidly accelerating application of laser ablation analyses, there is a great need for well-characterized reference materials that can serve multiple functions. Strontium (Sr) isotope analyses and U XANES demonstrate that these samples could be used as reference materials.

Short summary
This study investigates the coupling of climate and the carbon and hydrologic cycles in Asia ~ 113 million years ago to provide a more complete continental perspective on a dynamic climate interval associated with global ocean anoxic events. We find relatively cool conditions and a close coupling between the amount of CO2 in the atmosphere, air temperature and rainfall in Asia. To quantify these shifts, chemical measurements from continental soils which formed during this interval are utilized.

Short summary
This work presents the observation of the Early Jurassic terrestrial climate from the Sichuan paleobasin, southeastern China. Results manifest a (semi)arid climate in the study area, where the climate pattern is similar to the Colorado Plateau. The estimated atmospheric carbon dioxide concentration is 980–2610 ppmV with a mean of 1660 ppmV. The change of carbon dioxide concentration is compatible with the excursions of stable isotopes and seawater temperature from the coeval marine sediments.
This work presents the observation of the Early Jurassic terrestrial climate from the Sichuan...
