Discussion on structural evolution of Mesozoic Peninsular Malaysia

Article Abstract:

An analysis describing research on Malaya's structural evolution during the Mesozoic period is presented. It is shown that earlier research which discusses the Mesozoic Tembeling Formation presents many flaws concerning the area's stratigraphy and orogenesis. Some of the research's flaws involve discussion about the link between the Indosinian Orogeny and marine sedimentation, tectonic discontinuity separating Malaya from eastern Thailand and China and rock deformation styles found during the period.

The timing of quartz cementation in Mesozoic sandstones from Haltenbanken, offshore mid-Norway: fluid inclusion evidence

Article Abstract:

A study was conducted to examine quartz cementation temperature in Mesozoic sandstones. The study focused on stones found in the Haltenbanken region of Norway and employed microthermometry of fluid inclusions to test quartz overgrowth samples. Results show that the cementation occurred for a short duration and is estimated to have started within the last 5 Ma. These results imply that factors other than depth and temperature may have conditioned cementation.

Mesozoic radiolaran faunas from the Antarctic Peninsula: age, tectonic and palaeoceanographic significance

Article Abstract:

An analysis describing radiolarian faunas is presented. It is shown that new Radiolaran assemblages exhibited ages dating back to the latest Jurassic-earliest Cretaceous to at least by Albian. Diachronous sedimentation and deformation in the LeMay group possessed diachronous forms which are biased oceanwards to the northwest indicate that the group is an accretionary complex.
