Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. In order t...

Triassic strata are widely developed in the eastern part of Sichuan Basin. The Mingyuexia anticline and Huangnitang located structural belt develop Jialingjiang Formation to Xujiahe Formation. middle Leikoupo Badong on both sides synchronous heterogeneous strata. They distinguished regionally according their different sedimentary environments lithologic characteristics, phase transition boundar...

The excavation in the Wanfung area has provided evidence for at least three earthquake ruptures, including the 1999 ChiChi one. The Chi-Chi earthquake formed an obviously major reverse fault, backthrust, and several minor normal faults, accompanied by a teardrop-shape anticline in the fault tip. Paleoseismic ruptures I and II show the vertical displacement of 0.4 m and 1.2 m, respectively, whic...

Seismic tomography is a non-linear problem with a significant null-space. Our estimation problem often converges slowly, to a geologically unreasonable model, or not at all. One reason for slow or non-convergence is that we are attempting to simultaneously estimate reflector position (mapping velocity) and image our data (focusiing velocity). By performing tomography in vertical travel-time spa...

I realize and analyze a model-based joint tomography scheme in this paper. Surface reflection seismic data and VSP traveltimes are used simultaneously to invert the velocity by using an integrated inversion scheme. Since more data are used, the integrated tomography can obtain more accurate inversion results with lower uncertainty. Using identity operator as integration operator, I apply this m...
