The lower crust of the Mesozoic Sierra Nevada batholith was made up of high MgO, garnet-poor and low MgO, garnet-rich pyroxenites. Both groups are genetically linked and are collectively complementary to the mafic to intermediate Sierran plutons. High MgO pyroxenites represent high pressure cumulates from a mantle-derived hydrous basalt or basaltic andesite, resulting in derivative magmas havin...

Introduction: Defining the mineralogy and composition of martian mantle source regions has proved to be a difficult task because: (1) the martian sample set does not include samples of the mantle, and (2) many of the samples are either cumulates or are highly fractionated and therefore not in equilibrium with the mantle. Despite these complexities, isotopic evidence suggests that Mars had a mag...

A 32-year old single man presented with azoospermia and low semen volume which was noted one and half a year ago. Transrectal ultrasonography and seminal vesiculography were performed to evaluate ejaculatory duct obstruction, and transurethral resection of the ejaculatory duct was performed using a hybrid technique of holmium:yttriumaluminium garnet laser with monopolar transurethral resection ...

One characteristic of many subduction zone garnet peridotites is that they contain titanium-bearing phases not otherwise Ž . found in mantle rocks. In particular, titanoclinohumite TiCH andror its breakdown assemblage consisting of symplectic intergrowths of olivine and ilmenite is common in many of these bodies. The Alpe Arami garnet lherzolite of the Lepontine Alps, while lacking TiCH, displa...

Thermal conductivity at room temperature and pressure (k0), and heat capacity and total entropy as functions of temperature are calculated for majorite^pyrope garnets from new and previous infrared reflectivity and Raman scattering data. The thermodynamic properties, including the effect of cation disorder, vary by less than 4% over this binary, whereas k0 changes by s 400% due to cation disord...

We investigated calcite veins in two spinel-garnet peridotite xenoliths from the sub-Sierra Nevada mantle. These peridotites represent samples of the lithospheric mantle wedge beneath the Mesozoic California magmatic arc, as indicated by radiogenic isotopic ratios measured on clinopyroxenes separates (Sr/Sr8 Ma= 0.7058-0.7061, Nd/Nd8 Ma= 0.512538-0.512601). Mineral chemistry of the peridotite m...

W.L. Griffin, Suzanne Y. O'Reilly and N.J. Pearson GEMOC, Dept of Earth and Planetary Sciences, Macquarie University, NSW 2109, Australia [email protected] It has become conventional wisdom that xenoliths of eclogite and garnet pyroxenite derived from cratonic subcontinental lithospheric mantle (SCLM) represent fragments of subducted ocean floor, implying that the SCLM has grown by a litho...

BACKGROUND AND OBJECTIVES Hemangiomas remain a challenge for patients and plastic surgeons. Promising results have been reported using intralesional photocoagulation (ILP) for treatment. The objective of our study is to review the long term results of a large series of hemangiomas in patients treated by ILP. Materials (Subjects) and Methods: A retrospective review of 684 hemangiomas in patients...
