quartz (either as sand grains or as chert); anhydrite and gypsum may also occur. When using a single porosity log, the true porosity is calculated from interpolation between the values for the matrix mineral and the pore fluid (usually equated with mud filtrate, because of the shallow investigation of the porosity tools). Density log: Porosity is calculated from the massbalance .

· The precipitation of the main porosityoccluding cements (dolomite, anhydrite, and quartz) occurred early in the diagenetic history. Oxygen isotopes of dolomite (δ 18 O = to ‰ SMOW) suggest that meteoric water has played a major role throughout the diagenetic history, and that precipitation of these cements occurred at low temperatures (<80°C).

Dolomite that was sulfated by this process was regenerated for subsequent reuse as a sorbent to CaO . MgO by reductive decomposition in a fluidized bed. Regeneration was accomplished by the incomplete combustion of methane in a fluidized bed of sulfated dolomite to generate the heat and the required reducing gases for the reactions at 1010 to 1100/sup 0/C.

· Bimodal Dolomite (D6): This type of dolomite is characterized by a mixed mode of dolomite crystal sizes. It shows a mixed association of fine and medium crystalline mosaic ( Figure 13g ), or coarse and medium crystalline mosaic ( Figures 13h and 13i ); in both cases the finer part is characterized by anhedral to subhedral crystal shape, and the coarsest fraction is .

· Lithium obtained from salars is recovered in the form of lithium carbonate, the raw material used in lithium ion batteries. The production process is fairly straightforward and requires only natural evaporation, which leaves behind not only lithium, but also magnesium, calcium, sodium, and potassium.. The lithium content of ocean water is far lower, hovering .

Based on a series of experiments exploring the effects of temperature, leaching time, reagent/solid ratio and reagent strength, we propose an optimised method for selectively leaching Li isotopes from oxides using mol l −1 HH in 25% v/v HOAc with a reagent/solid ratio of 40 ml g −1 at room temperature (20 ± 2 °C) for 1 h. This leaching method applied on .

· Terence Bell. Updated on August 21, 2020. Most lithium is commercially produced from either the extraction of lithiumcontaining salts from underground brine reservoirs or the mining of lithiumcontaining rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.
