Shale, powdered

For the diffraction technique, —325-mesh shale powders were packed into the 7/8-in. diameter by 1/16-in. deep cavity of a 1-in. diameter aluminum holder and pressed smooth with a glass plate. A Norelco-Phillips diffractometer equipped with a Cu(Ka) source was used to analyze the samples. The diffractometer was driven at l°/min and the intensity response of the nonrotating sample recorded on a strip chart recorder. Peak assignments in both cases were made by visual comparisons with standards. 

Table 3 lists examples of more than a dozen different chemical types of river water. Although Ca and HCO j" are generally dominant, Mg dominance over Ca + can be found in rivers draining various lithologies such as basalt, peridotite, serpentinite, dolomite, coal, or where hydro-thermal influence is important (Semliki). Sodium may dominate in sandstone basins, in black shales (Powder, Redwater in Montana), in evaporitic sedimentary basins (Salt), in evaporated basins (Saoura), and where hydrothermal and volcanic influence is important (Semliki, Tokaanu). rarely exceeds 4% of cations, except in some clayey sands, mica schists, and trachyandesite it exceeds 15% in extremely dilute waters of Central Amazonia and in highly mineralized waters of rift lake outlets (Semliki, Ruzizi). 

In order to produce an aqueous solution which fulfills these criteria, 120 g each of basalt, quartz monzonite, and shale were ground to powders less than 37 m in diameter. Each of the samples was placed in two liters of distilled-deionized water which had been pre-equilibrated with an atmosphere containing 10 percent CO2, 90 percent Ar, and 10 ppm Og. The experiment was carried out in an inert atmosphere box at room temperature (26 + 2°C). Samples of the fluid (10 ml) were extracted at various times over a 35-day period and filtered (O.OSpm). Analyses for Na, K, Mg, Ca, Fe, Al, Si02 (aq). Eh, and pH were made on each sample. The experiment was terminated at the end of 846 hours and analyses for HCO3, SO4, and Cl were made on each of the fluids.

I got up, took a knife, and chipped away at the seal joining the receiving flask to the distillation tube. Once they were separated, my clammy hands put the neck of the jar of saltpeter to the receiver. My heart thudded. I was committed. The jar tilted and the white powder began its slide downward. Then one vessel was vertical over the other and the saltpeter was plunging into the distillate. I saw the rose again, deep pink among its inverted crown of sepals. I remembered that Shales had once been in the laboratory and that he had stroked my neck.

The x-ray analyses were obtained using powder camera and diffractometer techniques. In the former, powdered shale was loaded into a glass capillary which then was exposed to 20 hr of Cu(Ka) radiation. The x-ray pattern was taken with a standard Norelco 114.6-mm diameter powder camera equipped with a nickel filter.

The shale sample contained 20.4% organic matter Cl) It was powdered to -100 mesh (Tyler). In most cases the bitumen was isolated by 100 hr Soxhlet extraction either with benzene or with a mixture of benzene and methanol (1 1).
