FetKin是一个c++程序，用于在二维地质剖面上正演模拟热年代学年龄。各种温度计的建模年龄是根据时间-温度历史计算得出的，这些时间-温度历史是由商业平衡重建软件（2DMove）和温度有限元计算获得的变形建模运动学耦合而成的。附加功能包括适应(1)拓扑地形的平滑变化；(2)岩石物性变化的影响；(3)裂变径迹年龄和长度分布以及磷灰石和锆石(U-Th)/He和白云母体系的多动力学模拟。对侵蚀参数和材料性能影响的联合一阶分析改进了年龄预测，并允许基于其模拟的热历史对观测到的冷却年龄进行更完整的分析。因此，本文提出了一种新的软件工具，该工具已被开发为用于构建本卷中所示的运动学恢复的方法的基本支持，这是哥伦比亚东科迪勒拉和Llanos山麓盆地石油系统建模和预测的基本输入。
FetKin is a C++ program for forward modeling thermochronological ages on a two-dimensional geological cross section. Modeled ages for various thermochronometers are computed from time–temperature histories that result from coupling the modeled kinematics of deformation obtained from commercial software for balanced reconstructions (2DMove) and a finite element computation of temperatures. Additional capabilities include the ability to accommodate (1) a smooth change of topological relief; (2) the influence of variation in rock physical properties; and (3) multikinetic modeling of fission-track ages and length distributions, as well as apatite and zircon (U-Th)/He and muscovite systems. A joint first-order analysis of the impact of erosion parameters and material properties improves age predictions and allows for a more complete analysis of observed cooling ages based on their modeled thermal histories. Thus, this paper presents a new software tool that has been developed as a basic support for the methodological approach used to build the kinematic restorations shown in this volume, which are the basic input for petroleum systems modeling and prediction in the Colombian Eastern Cordillera and Llanos foothills basin.
