چکیده

This paper evaluates previously proposed diagnostic criteria that can be used to determine whether or not there is active migration of the opal-A opal-CT transition zone (TZA/CT). The are based on interpretation 2D and 3D seismic surveys therefore geometrical. They involve an assessment relationship TZA/CT with polygonal fault systems, differential compaction structures tectonic folds. most robust evidence for inactive ‘reaction front’ between bearing sediments discordance relative present-day isotherms. Any these may persuasive as upward arrest diagenetic transformation at a regional scale, but actual truncation modern seabed definitive arrested diagenesis. study argues solely single criterion independently reliable indicator current state silica transition. As conclusion, analysed seismic/structural should synthesised provide more credible use data reconstruction history opaline offers new approach diagenesis scale.

Silent brain infarcts: a review of MRI diagnostic criteria.

BACKGROUND AND PURPOSE Silent brain infarcts (SBIs) have been recognized as common lesions in elderly subjects and their diagnosis relies on brain imaging. In this study, we aimed to evaluate the different MRI parameters and criteria used for their evaluation in the literature to better understand the variation across studies and related limitations. METHOD Original MRI studies of SBI perform...
