We provide arguments in favour of impact origin of a 200 km suspected impact crater Kotuykanskaya near Popigai, Siberia, Russia. We use the gravity aspects (gravity disturbances, the Marussi tensor of the second derivatives of the disturbing geopotential, the gravity invariants and their specific ratio, the strike angles and the virtual deformations), all derived from the combined static gravity field model EIGEN 6C4, with the ground resolution of about 10 km and a precision of about 10 milliGals. We also use the magnetic anomalies from the model EMAG2 and emphasize the evidence of much deeper sources in the suspected area, constraining the impact origin of this structure.

我们提供了支持在俄罗斯西伯利亚Popigai附近200公里可疑撞击坑Kotuykanskaya撞击起源的论点。我们使用重力方面（重力扰动，扰动地势的二阶导数的Marussi张量，重力不变量及其比值，触角和虚拟变形），所有这些都来自于组合的静态重力场模型EIGEN 6C4，地面分辨率约为10 km，精度约为10毫加仑。我们还使用了EMAG2模型的磁异常，并强调了可疑区域中更深的震源的证据，从而限制了该结构的碰撞成因。
