The Geologic Time Scale and the Italian stratigraphic record

The construction of the Geologic Time Scale (GTS) is a titanic scientific challenge that has been under way for two centuries and will require much dedicated effort in the future. Italy preserves a paramount stratigraphic record of Mesozoic and Cenozoic marine sediments that have been significant in the development of the modern GTS. The Italian stratigraphic record has been histori-cally important in introducing and defining the standard Chronostratigraphic Units (CUs) of the Neogene and Quaternary. Pelagic successions from Northern Apen-nines and Southern Alps have been used in the seventies for integrating the late Cretaceous-Paleogene Geomag-netic Polarity Time Scale (GPTS) with planktonic microfossil biostratieraohv and standard CUs. This was a major contribution to the construction of a new gener-ation of GTS based on integrated magnetobiochronol-ogy. The middle Miocene to early Pleistocene marinerecord from Sicily and southern Italy has been funda-mental for establishing the recently developed Astro-nomical Time Scale (ATS). In prospect, there are many potentials still to be exploited in the Italian marine stratigraphic record for implementing the GTS by defin-ing GSSPs of various CUs, improving magneto-biochronology and extending downwards the ATS.

地层倾角测井矢量图模式识别与构造解释系统

本文介绍了地层倾角测井矢量图模式识别与地质构造解释系统的设计原理和基本方法。文中利用Ｆｉｓｈｅｒ方法划分构造段，利用极差分层和归并，通过模糊数学的方法进行模式识别，通过井钻的模式识别结果给出井位所在地的地质构造解释。本系统已在ＩＢＭＰＣ／ＸＴ及其兼容机上实现，对胜利油田和中原油田的２３个实际测井数据进行了实验，判别和解释正确率达到９０％。     

试论海岸带资源资产的产权界定和产权管理

本文对海岸带海资源的产权界定和产权管理进行了初步的讨论。在马克思产权思想导下，借鉴西方现代产权理论，界定我国公有制前提下的产权概念。理顺产权关系，建立新型资源管理体制，是海岸带资源管理立法、改革的一个新思路。
