The Rb-Sr and Sm-Nd isotopic ages were determined for two Apollo 15 pristine lunar breccias, 15445 and 15455, collected near Spur Crater on the Apennine Front. The analyses of mineral separates from two norite samples in breccia 15445 showed that the

New Pb, Sr and O isotopic analyses of rocks from the Skaergard intrusion indicate the following: (1) initial 87 Sr/ 86 Sr of the gabbroic magma was less than or equal to 0.7041; (2) limited contamination of magma with crustal Sr and Pb may have occur

Sm-Nd data for authigenic ferromanganese sediments from the oceans indicate that the Atlantic, Pacific, and Indian Oceans each have a distinct range in Nd isotopic composition which are characteristic of each ocean basin and reflect the dissolved loa

The Newer Volcanics Province of Victoria and South Australia consists of a major region of mainly alkaline basalts within which are two restricted areas containing strongly differentiated flow‐rocks. Typical alkalic basalts from this widespread pro

The petrology and chronology of early lunar crust is examined using the least equivocal of the available petrographic and age data on lunar rock samples, and the possible processes which produced the lunar crust are discussed. The results suggest tha

We present here a brief description of geological relations and results of lead isotopic analyses of eight whole-rock samples of Precambrian gneiss from an area near the Skaergard Intrusion in the Kangerdlugssuaq region of eastern Greenland.
