Abstract: The main aim of this work is to understand the distribution of minerals by obtaining a shallow velocity structure around the Karatungk (喀拉通克) region. Data were acquired in 2009 by a denser array in deploying a transportable seismometer with 4.5 Hz vertical geophone. All the P-wave arrival times are picked automatically with Akaike information criterion, and then checked man- machine interactively by short-receiver geometry. The database for local active-source tomographic inversion involves 4 241 P-wave arrival time readings from 96 shots and three quarry blasts. Checkerboard tests aimed at checking the reliability of the obtained velocity models are presented...
