“…5) that has yielded conventional K/Ar whole-rock ages in two clusters around 3.6 Ma and 2.5 Ma (Nakata et al, 1993). The alkali basalt includes xenoliths derived from the lower crust and upper mantle (Nakata, 1980;Wilshire et al, 1988) and is distributed along the Silver Creek fault and the southern part of the central Calaveras fault (Fig. 5A), suggesting that the fault zone served as a conduit for lava rising from great depth prior to overthrusting by the younger faults.…”

Santa Clara Valley is bounded on the southwest and northeast by active strike-slip and reverse-oblique faults of the San Andreas fault system. On both sides of the valley, these faults are superposed on older normal and/or right-lateral normal oblique faults. The older faults comprised early components of the San Andreas fault system as it formed in the wake of the northward passage of the Mendocino Triple Junction. On the east side of the valley, the great majority of fault displacement was accommodated by the older faults, which were almost entirely abandoned when the presently active faults became active after ca. 2.5 Ma. On the west side of the valley, the older faults were abandoned earlier, before ca. 8 Ma and probably accumulated only a small amount, if any, of the total right-lateral offset accommodated by the fault zone as a whole. Apparent contradictions in observations of fault offset and the relation of the gravity fi eld to the distribution of dense rocks at the surface are explained by recognition of superposed structures in the Santa Clara Valley region.

“…In the world, oil or gas volcanic reservoirs have been discovered (Sruoga et al, 2004;Mitsuhata et al, 1999;Levin, 1995;Sakata et al, 1989;Nakata, 1980;Sembodo, 1973). In the faulted depression of eastern China, there is also widely exiting oil or gas of Early Cretaceous in Xujiaweizi faulted depression of southeastern Songliao basin and Jurassic in western Liaohe depression of Bohaiwan basin volcanic rocks (Feng, 2008(Feng, , 2006Zhao et al, 2008;Zhang et al, 2006;Wu et al, 2003;Gu et al, 2001).…”

Recently, volcanic gas reservoirs in Yaoyingtai (腰英台) and Daerhan (达尔罕) tectonic belts in Changling (长岭) faulted depression of southeastern Songliao (松辽) basin have been discovered.Based on the compositions and isotopic values, the natural gas is characterized by high content of methane, low content of C 2 + , and C 1 /C 1-5 beyond 0.95. Also, the natural gas contains nonhydrocarbons including carbon dioxide with the content from 20% to 40% and minor amount of N 2 . Combined with the isotopic values, the natural gas is generated by humic kerogen and coal-derived type, but in Daerhan, the natural gas is probably mixed by oil type gas. From the measurement of lithology and fluid inclusions in volcanic rocks, the bitumen, liquid hydrocarbon, and gas hydrocarbon inclusions are present. Through the analysis of the single gas inclusion in volcanic reservoir, the content of carbon dioxide is low, so the carbon dioxide and hydrocarbon gas of the reservoirs are not accumulated at the same time. In addition, minor amount of bitumen in the reservoirs is formed by thermal evolution of the crude oils sourced from the Yingcheng (营城) Formation mudstones through the characterizations of the biomarkers. The distribution of homogenization temperatures presents two peaks, one with the liquid hydrocarbon filling stage, and the other with gas filling stage. However, in Daerhan tectonic belt, the second peak is gas and carbon dioxide mixed filling period probably. Combined with the This study was supported by East China Branch of SINOPEC

“…North of Coyote Lake the Hayward fault branches westward from the Calaveras fault and trends parallel to the san Andreas fault. Right-lateral movement and fault creep have been documented by the offset of correlative rocks (Nakata, 1977), streams (Radbruch-Hall, 1974}, and streets, stdewalks, and curbs. (Rogers and Nason, 1971;Radbrucll-Hall, 19.741.…”
