Assessing Ar transport paths and mechanisms in the McClure Mountains hornblende
Article Abstract:
Hydrothermal cold-seal bomb experiments and 39Ar/40Ar dating extraction of the McClure Mountains hornblende reveal that zones abundant in planar defects play a crucial role in inducing Ar loss and etching nucleation. Transmission electron microscopy of heated/unheated crystals shows that stepwise heating age spectrum is best in reproducing features that are compatible with concentric diffusive zonation. Bulk Ar loss in the experiments may be attributed to intergrowths of low Ca/K minerals such as biotite and imperfect mineral separation creates discordance in the hornblende spectra.

The increased need for stronger anti-child pornography statutes
Article Abstract:
Congress should add stronger strict liability language to the 1984 Child Protection Act provision controlling child pornography distribution, rather simply relying on the Supreme Court's X-Citement Video decision leaving the provision intact. A stronger statute, modelled on the food and drug strict liability laws, would allow distribution of constitutionally-protected material while barring obscene child pornography distribution and holding offenders strictly liable for the age of the performers.
