The ground state absorption spectra of [NiF6]4 clusters with orthorhombic symmetry (Ni2+ in NiF2 crystal and Ni2+-doped ZnF2 crystal, D2h point group) are theoretically calculated and assigned by diagonalization of 45 × 45 complete energy matrix for 3d8 configuration and the spin-Hamiltonian (SH) parameters (zero-field splitting D and E, and g factors gx, gy, gz) are studied by use of high-order perturbation method, in the frame of semi-empirical molecular orbital (MO) scheme based on strong crystal field framework. In those energy matrix, all the configuration interactions though the cubic crystal field (CF), the orthorhombic crystal field, the Coulomb interaction are taken into account. The calculated results are in good agreement with the experimental data. The local structure (bond length and bond angle) of [NiF6]4 clusters are determined, and the results shows that the structure data given by Stout are more plausible than those given by Baur. © 2013 Elsevier B.V.

This paper examines the induced polarization anomalies characteristics of the Zhongyang copper deposit in Qinghai Province to provide the basis for the follow-up project, and at the same time provide some useful experience for the geophysical exploration of the same type of deposits. By using the induced polarization method in the mining area, the delineation of IP anomalies is carried out, and the relationship of IP anomaly to the occurring copper ore bodies as lens and the ore-controlling structure space distribution is analyzed. The characteristics and distribution of the induced polarization anomalies on the Zhongyang copper deposit obviously reflect the copper ore bodies as lens and coppercontaining iron ore beds. Based on the principle to infer from the known to the unknown interpretation of geophysical anomalies, the paper explains and infers that the received polarization anomaly is the reflection of the ore body, such as, the inferred No. I abnormally is caused by the copper-containing strata and verified and controlled by the engineering project.

By using the shallow seismic reflection method, this paper studies the surface, the space location and distribution pattern of the Gengda-Longdong fault to provide evidences for the evaluation of the recent activities of the fault and the assessment of the maximum earthquake-triggering capacity. Aiming at the problems that the bedrock interface of the Longmenshan area is buried shallow, and the effective signals from the shallow source are easily interfered by strong wave, this paper uses the multi-channel short arrangement receiving and the way of observing the common reflection points for many times in the seismic exploration work to get shallow seismic reflection profile image after a suitable data processing. The image reveals the spatial distribution position and the near-surface structure of the Gengda-Longdong fault and its branches in the Ruobigou area of Longdong town in Baoxing. The Gengda-Longdong fault is an active thrust fault striking in NE, dipping in NW, and with a dip angle about 65°∼80°. There develop T1 and T2 terraces of the Baoxing river at the location where the fault passes by, but no large-scale river gullies and faulted river terraces develop there.

For the buried active fault in Qingchuan County district of Sichuan Province, the authors use the integrated geophysical exploration method to identify the distribution conditions of the buried active fault in the city districts of the Pingwu-Qingchuan, the specific location and associated parameters of the main fault and its branches through the trench excavation verification to be reliable. There are three hidden faults in Qingchuan County districts, the most northern one is the main fault in the Pingwu-Qingchuan fault. Its general trend is NEE. The middle and south branches are subbranches of the fault rupture of the Pingwu-Qingchuan fault. Their trends are NE. Their middle and south branches fault ruptures of the 3 buried faults extend to the pebble bed under 2 m beneath the surface.

In order to determine the distribution and location of the copper deposit, the magnetic anomalies are observed by using ground high-precision magnetic survey method. The occurrence position of ore (mineralized) bodies, the space characteristics of ore-controlling structure, and the characteristics of structure and rock mass can be inferred through analyzing the characteristics of the ground high-precision magnetic survey anomaly and explaining the geological reasons of the magnetic anomaly. Thereby the distribution and location of the copper deposit have been determined. The result is verified by drilling afterwards and is correct.
