| 英文摘要 | In this study, the ion concentrations (K+, Na+, Ca2+, Mg2+, Cl-, SO42-, Br-, NO3-, and B3+) and boron isotope compositions (delta B-11) of 34 halite and brines samples from the Neoproterozoic Salt Range Formation, Punjab, Pakistan were studied. Relation among B3+ vs. Mg2+, B3+ vs. SO42-, delta B-11 vs. B3+, and delta B-11 vs K+ were observed, they indicated that these elements originate from multiple sources and the end members were identified as seawater, B desorption from clays, and meteoric precipitation. Halite samples of the area under study displayed a Na-HCO3-type to Ca-Cl type sedimentary basin of deposition, on delta B-11 vs. 1/B plot. Molar ratios of B/Cl vs. delta B-11 revealed the addition of B in some of the studied samples from desorption of clay minerals. This type of diagenetic desorption of B from clays is the consequence of a stress driven mechanism, generated in the proximity of a decollement zone. Results confirm that the number of B stable isotopes that fractionate between the brine and the halite is low. The halite delta B-11 from the Salt Range Formation vary from +2.1 to +24.4 parts per thousand, compared to +17.3 to +26.1 parts per thousand in the salt pool brines, and suggest that boron isotope compositions are controlled by the delta B-11 of the B sources. The positive relationship between the boron content and the corresponding delta B-11 indicates a higher salinity and drier paleoclimate conditions during the formation process, associated with a high evaporation rate in the Late Neoproterozoic time. Presence of elevated delta B-11 in the present study, demonstrate compatibility with other marine basins of the world, arising the need for further investigations to better characterize the B-11-enriching processes. |
