An experimental study of the partitioning of a rare earth element (Gd) in the system diopside—Aqueous vapour

The partitioning of Gd in the experimental system diopside-aqueous vapor as a function of temperature, pressure, composition of the phases, time, grain size, solid-liquid ratio and Gd concentration has been investigated. A radioactive tracer measurement was used to determine Gd concentration in the separated phases. Diposides were reacted with...

Fresh lunar impact craters: Review of variations in size

Thirty-three morphologic characteristics are reviewed for fresh lunar impact craters wide than1 km. Bar graphs express the way each characteristic varies with crater size. The features are grouped as crater structure, ejecta, and downhill flow features. Major structural transition occur at diameters of about 15 and 200 km. Details of the ejecta...

Lunar basin formation and highland stratigraphy

Multiring impact basins, formed after solidification of the lunar crust, account for most or all premare regional deposits and structures expressed in the lunar landscape and for major topographic and gravity variations. A fresh basin has two or more concentric mountain rings, a lineated ejecta blanket, and secondary impact craters. Crackled...

Origin of Franciscan melanges in Northern California

In northern California, chaotic Franciscan melange occurs beneath the overlying ophiolite and Great Valley Sequence. Identical melanges occur to the west, separating well-bedded, coherent Franciscan units that differ markedly in age. Detailed studies in several places indicate that these melanges mark the boundaries of imbricate thrust sheets, and...

Some interpretations of sequential bid pricing strategies

This note provides an alternative interpretation for sequential bid pricing strategies as initially formulated by Kortanek, Soden, and Sodaro [Kortanek, K. O., J. V. Soden, D. Sodabo. 1973. Profit analysis and sequential bid pricing models. Management Sci.20 (3, November) 396–417. In particular, bid prices obtained from the sequential...

Geologic Exploration of Taurus-Littrow: Apollo 17 Landing Site

Apollo 17 landed in a deep graben valley embaying the mountainous highlands southeast of the Serenitatis basin. Impact-generated breccias underlie the massifs adjacent to the valley, and basalt has flooded and leveled the valley floor. The dark mantle inferred from orbital photographs was not recognized as a discrete unit; the unusually thick...
