Abstract

This study implements the least-squares inversion method for solving the exhumation history from thermochornologic age-elevation relationship (AER) based on the linear equation among exhumation rate, thermochronologic age and total exhumation from the closure depth to the Earth surface. Modelling experiments demonstrate the significant and systematic influence of initial geothermal model, the a priori exhumation rate and the time interval length on the a posterior exhumation history. Lessons learned from the experiments include that (i) the modern geothermal gradient can be used for constraining the initial geothermal model, (ii) a relatively higher a priori exhumation rate would lead to systematically lower inversion results, and vice versa , (iii) the variance of the a priori exhumation rate controls the variation of the inverted exhumation history, (iv) the choice of time interval length should be optimized for resolving the potential temporal changes in exhumation. Putting together these findings, we propose a new stepwise inversion modeling strategy for optimizing the model parameters to mitigate the model dependencies on the initial parameters. Finally, we use three examples of different exhumation rates and histories for method demonstration. It is shown that our new modelling strategy produces geologically reasonable exhumation histories and geothermal gradients that are consistent with both the observed AER and modern geothermal data. The code and data used in this work is available in GitHub (https://github.com/yuntao-github/code4modelAER). [ABSTRACT FROM AUTHOR]

15. Stereoselective Synthesis of (E)-3-Alkylideneoxindoles viaGold(I)-Catalyzed Cross-Coupling of 3-Diazooxindoles with Diazoesters

Abstract

A versatile gold(I)-catalyzed cross-coupling reaction of 3-diazooxindoles with diazoesters has been presented, affording (E)-3-alkylideneoxindoles stereoselectively. Density functional theory calculations rationalized the chemo- and stereoselectivity of the reaction, which was in good agreement with experimental observations. In addition, (E)-3-alkylideneoxindoles were converted into their (Z)-isomers under UV-irradiation facilely, indicating the great advantage of this approach in stereoselective synthesis of both (E)- and (Z)-3-alkylideneoxindoles.
