| 英文摘要: | Depositional sequences capped by peritidal carbonates and breccias on the Aptian Adriatic carbonate platform, Croatia, were studied to evaluate evidence for glacioeustasy within an age framework constrained by carbon-isotope chemostra-tigraphy. Sequence Adi (17-60-m [56-197-ft] thick; uppermost Barremian-lower Aptian) is dominated by shallow subtidal parasequences. Sequence Ad2 (7-13-m [23-43-ft] thick; lower Aptian-lowermost upper Aptian) contains oceanic anoxic event (OAE) la, associated with lagoonal laminated carbonates. Sequence Ad3 (3-8-m [10-26-ft] thick) probably is lower upper Aptian and likely is separated by a major hiatus from sequence Ad4 (8-20-m [26-66-ft] thick; uppermost Aptian), which spans OAElb. Both Ad2 and Ad3 are dominated by peritidal parasequences updip in the lower transgressive systems tract and upper highstand systems tract and by subtidal parasequences elsewhere, whereas sequence Ad4 is dominated by shallow subtidal parasequences. Low accommodation rates (4.0-6.0 cm [1.6-2.4 in.] in the earliest Aptian, decreasing to approximately 1.0 cm/k.y. [0.3 in./k.y.] later) promoted widespread breccia development during relative sea level falls, aided by tectonic warping. The sequence-capping breccias, eccentricity-dominated cyclicity, restriction of peritidal facies to late highstands, and coeval off-shelf oxygen-isotope records all suggest that sea level falls occurred during times of cooling and had a significant glacioeustatic component. These intermittent cooler periods and continental ice buildup punctuated the Aptian greenhouse climate. © 2012. The American Association of Petroleum Geologists. All rights reserved. |
