Oligocene partial melting in the Takab metamorphic complex, NW Iran: Evidence from in situ U-Pb geochronology [PDF]
Journal of Sciences, Islamic Republic of Iran, 2013 U-Pb ages obtained on zircons from the investigated migmatites place new constraints on the evolution of the crustal rocks in the Takab area. SHRIMP U-Pb dating of inherited zircon in the melanosome parts of mafic migmatites from the Takab complex gives ...

Malignant melanoma of the urethra: a rare histologic subdivision of vulvar cancer with a poor prognosis [PDF]
, 2012 Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that ...

Migmatites, Melting, and Metamorphism
Eos, Transactions American Geophysical Union, 1985 This is a praiseworthy collection of papers that illustrates the great range of interests necessary to understand migmatite genesis. The strength of the collection lies in its broad approach to the study of migmatites and its emphasis on the link between “igneous” and “metamorphic” processes.

Understanding Geological Data Distribution and [PDF]
, 2007 Insufficient field test results and a sufficiently large degree of spatial disorder exhibited by melt flow properties on sheared migmatites leads us to use stochastic methods to describe the distribution and orientation of leucogranitoid veins in ...

CO2-rich fluid inclusions in greenschists, migmatites, granulites, and hydrated granulites [PDF]
Data was discussed from several different terrains in which CO2-rich fluid inclusions occur despite parageneses that predict the presence of H2O-rich fluids.
