摘要:... Precise 40 Ar/ 39 Ar dating and determination of hydrogen and oxygen isotopes of supergene jarosite can not only place tight constraints on the timing and history of continental weathering and supergene enrichment of sulfide ore deposits, but also shed significant insights i...

摘要:Abstract(#br)We report new 40 Ar÷ 39 Ar dating results obtained from total fusion and incremental-heating analyses of sanidine and biotite from three tuffs found interbedded within the fossil-bearing deposits of Liaoning, northeast China. The first is a new sample of the Be...

摘要:Abstract(#br)Hydrothermal clay minerals that formed in the main metallogenic stage of the Changkeng disseminated-type gold deposit in central Guangdong were analyzed by the 40 Ar/ 39 Ar laser probe. The results give Ar-Ar isochron ages of 109.9 ±1.4 to 110.1 ±1.3 Ma, which ar...

摘要:... This study obtains two isotopic ages from a quartz vein sample associated with bitumen in a reverse fault located in the Bankeng paleo-reservoir on the southern margin of the middle Yangtze block (the northern margin of the Jiangnan-Xuefeng uplift) by inclusion 40 Ar/ 39 Ar s...

摘要:... In order to date the thrusting events, syntectonic muscovite and biotite grains are respectively analyzed with normal 40 Ar/ 39 Ar dating and laser 40 Ar/ 39 Ar dating, which yield 2 isochron ages, i.e. 193.74 ± 3.88 Ma and 121.6 ± 1.6 Ma. These ages suggest that faults...

摘要:... A muscovite 40 Ar/ 39 Ar plateau age of 128 Ma was obtained from mylonite in the later ductile shear zone. Three muscovite samples separated from mylonites of 3 localities in the earlier ductile shear belts yield 40 Ar/ 39 Ar plateau ages of 192.5±0.7 Ma, 189.7 ± 0.6 Ma...

摘要:... 40 Ar/ 39 Ar incremental heating results on groundmass selected from the samples show that the age spectra are meaningless geologically. However, singe crystal total fusions of CO 2 lasing on the sanidine separates could yield rational 40 Ar/ 39 Ar results and distinguish ...

摘要:Abstract(#br)Using laser 40 Ar/ 39 Ar dating method, we have gotten the metamorphic ages of lawsonite blueschist and epidote blueschist from Jiuquan, northern Qilian Mountain, NW China. The high quality laser 40 Ar/ 39 Ar dating of glaucophane from lawsonite blueschist gives ...

摘要:... 40 Ar/ 39 Ar dating results show that Sanbaoying rocks were erupted at 116.0 ± 0.3 Ma. Combination of paleomagnetic results and 40 Ar/ 39 Ar dating indicates that the reversed event recorded in Sanbaoying lavas corresponds to the ISEA event in the CNS. Our age determina...

摘要:... Laser probe step-heating analysis of supergene hollandite and cryptomelane samples collected from central Queensland, Australia, yield well-defined plateaus and consistent isochron ages, confirming the feasibility dating very-fined supergene manganese oxides by 40 Ar/ 39 Ar...
