Can calcite U-Pb dating be used to constrain the age of oceanic crust?

The manuscript “Calcite U-Pb dating of altered ancient oceanic crust in the North Pamir, Central Asia” by Rembe et al presents a new application of U-Pb dating of calcite to constrain the age of oceanic crust, applied to addressing questions of the age and lateral continuity of ophiolite belts in the Pamir and Western Kunlun.

Can calcite U-Pb be used to constrain the timing of Carlin-type gold deposits?

This study shows that the calcite U-Pb method can be used to constrain the timing of Carlin-type gold deposits and successive hydrothermal events. You do not currently have access to this article.

Can calcite be used to constrain the ages of hydrothermal processes?

Recent advances in U-Pb methods show that calcite can be used to constrain the ages of hydrothermal processes, but few studies have been applied to ore deposits.

Are calcite cements in the Urgonian microporous limestone of southeastern France U-Pb-dated?

In this study we performed absolute U-Pb dating of calcite cements occurring in the Urgonian microporous limestone (northern Tethys margin) of southeastern France.

Is the Urgonian Limestone a microporous carbonate reservoir?

The studied samples belong to the Urgonian Limestone (UL) formation of Barremian–Aptian age located in southeastern France ( Fig. 1 ), considered to be a good analog of major microporous carbonate reservoirs in the Middle East ( Borgomano et al., 2013 ).

Are chronological constraints reliable for the formation of microporosity in Limestone reservoirs?

However, placing reliable and accurate chronological constraints on the formation of microporosity in these reservoirs is a major challenge. In this study we performed absolute U-Pb dating of calcite cements occurring in the Urgonian microporous limestone (northern Tethys margin) of southeastern France.

How many generations of calcite cement are there?

Two main generations of calcite cement, S1 and S2, have been documented in the formation, based on petrographical and textural evidence showing a continuum from the S1 microsparite to the S2 blocky calcite. Note that the S1 phase is too small and inclusion rich to be subsampled for U-Pb dating purposes.

What can radiometric dating tell us about diagenetic cements in the Middle East?

The successful application of U-Pb dating of diagenetic cements in the UL highlights the great potential of radiometric dating to help unravel the complex diagenetic histories and subsequent architecture heterogeneities in carbonate reservoirs, especially those from the Middle East.
