description

Bakalaura darbā veikts pētījums par Ežurgu klintīs un Zivtiņu klinšu dienvidu daļā atsegto devona Burtnieku svītas nogulumiežu sedimentācijas apstākļiem, balstoties uz lauka un laboratorijas darbos iegūtajiem novērojumiem un datiem. Darbs pamatojas uz lauka darbiem, kuru ietvaros tika ievākti pētījumam nepieciešamie dati, 4 atsegumu ģeoloģisko griezumu izveidi, slīpslāņojuma mērījumiem, granulometrisko analīzi, kā arī fāciju un fāciju secību analīzi. Iegūtie dati un to interpretācija ļauj secināt, ka Ežurgu klintīs un Zivtiņu klinšu dienvidu daļā atsegtie devona Burtnieku svītas smilšainie nogulumi veidojušies migrējošās zemūdens grēdās, kas pārvietojušās plašā kanālā ar lēzenu gultni. Pēc tam, domājams, attīstījies jauns kanāls, kurā uzkrājušās mālaini aleirītiskas nogulas. Atslēgas vārdi: sedimentoloģija, Živetas stāvs, smilšakmens, granulometriskā analīze, deltas kanāli.
