Sequence stratigraphy, ib ceg ntawm sedimentary stratigraphy, cuam tshuam nrog qhov kev txiav txim, lossis ib ntus, nyob rau hauv uas depositionally cuam tshuam stratal successions (lub sij hawm-Rock) units tau nteg nyob rau hauv qhov chaw muaj los yog chaw nyob. Lub chronostratigraphy ntawm sedimentary pob zeb lem hloov lawv tus cwj pwm los ntawm lub sij hawm geological.
Yuav ua li cas yog cov units ntawm sequence stratigraphy?
Ib kab ke stratigraphic moj khaum tej zaum yuav muaj peb hom sib txawv ntawm cov kab ke stratigraphic unit, uas yog sequences, systems tracts, and parasequences. Txhua hom chav nyob yog txhais los ntawm cov qauv stratal stacking thiab bounding nto.
Vim li cas cov kab ke stratigraphy tseem ceeb rau roj av?
Cov txheej txheem stratigraphic ib ntus muab (1) ib txoj hauv kev zoo dua rau kev soj ntsuam cov kab dej hauv reservoir txuas ntxiv thiab cov lus qhia sib txawvthiab (2) txhim kho txoj hauv kev rau kev kwv yees lub hauv paus, qhov chaw, thiab sealing facies deb ntawm kev tswj kom zoo.
Dab tsi yog stratigraphy hauv geology?
Stratigraphy yog lawv faib cov txheej txheem sib txawv lossis txheej txheej ntawm sedimentary deposits, thiab hauv cov pob zeb sedimentary lossis txheej pob zeb volcanic. Daim teb no yog ib qho tseem ceeb rau kev nkag siab txog keeb kwm geological thiab tsim lub hauv paus rau kev faib cov pob zeb rau hauv cov chav sib txawv uas tuaj yeem ua tau yooj yim mapped.
Leej twg invented sequence stratigraphy?
Kev sib tw stratigraphy yog ib txoj hauv kev tsis ntev los no rau stratigraphicKev txhais lus, pioneered los ntawm Peter Vail nyob rau hauv nruab nrab 70's (Vail li al 1977), uas piav qhia txog cov geometries nyuaj uas sediments tau txais thaum lawv sau cov chaw nyob rau hauv cov lus teb rau kev hloov pauv ntawm cov sedimentation, tectonic thiab eustatic zog.
