Beachrock as a sea-level indicatoran indicator of former sea levels should be used in conjunction with other types of evidence. Care needs to be taken not to confuse beachrock . with other cemented materials which may outcrop in the intertidal zone.被告 发表于 2025-3-23 15:39:35
Introductionnsuming SL-study results relates primarily to three factors: (i) the wide spectrum and interrelationships of possible causes of SL change, (ii) the variation in the nature of SL change evidence (records), and (iii) the fact that SL itself is a variable in process-response systems that are studied for reasons of applied or academic interests.言外之意 发表于 2025-3-23 21:20:57
Corals and reefs as indicators of paleo-sea levels with special reference to the Great Barrier Reefheir growth environment which may be determined by careful analysis. Similarly, with careful choice and preparation of samples, corals provide excellent material for a variety of radiometric dating techniques.Blasphemy 发表于 2025-3-24 00:00:31
Submerged forests as sea-level indicatorsregressions. Conclusions reached are 1) that the lowest levels of tree growth can be closely related to a point between the local mean high water spring tide and highest astronomical tide and 2) that the preservation of trees in submerged forests is an accurate reflection of past sea levels.债务 发表于 2025-3-24 04:54:35

Elevation and age relationships: raised marine deposits and landforms in glaciated areas: Examples bit specify a former sea level? 3) what are the actual or inferred relative ages of the sediment or features? and, finally, 4) what methods can be used to portray the patterns of relative sea-level change and shoreline deformation??Fracture 发表于 2025-3-24 11:23:30

Elevation and age relationships: raised marine deposits and landforms in glaciated areas: Examples bese questions are: 1) what is the relationship of the deposit to glacial ice? 2) what is the present altitude of the deposit or landform and how does it specify a former sea level? 3) what are the actual or inferred relative ages of the sediment or features? and, finally, 4) what methods can be used
