Timbas ezera nogulumi un to paleobotāniskā analīze

subject

description

Bakalaura darbā pētīti Timbas ezera nogulumi, veicot nogulumu zondēšanu, urbšanu, iegūtos ezera nogulumu paraugus analizējot ar sporu-putekšņu analīzi, lai noskaidrotu nogulumu paleobotānisko sastāvu. Sporu-putekšņu analīzes rezultāti ļauj secināt, ka Timbas ezera pētītie nogulumi uzkrājušies kopš leduslaikmeta beigu posma, kad ezera apkārtnē valdīja subarktiski apstākļi, vēl nebija mežu, cauri klimatiskajam optimumam, kad veģetācijā dominēja platlapji, un holocēna beigu posmam līdz mūsdienām, kad mežu sastāvā palielinājās skujkoku īpatsvars. Bakalaura darbs ietver 56 lapaspuses, ievadu, 4 nodaļas, secinājumus, literatūras sarakstu, 14 attēlus, 3 tabulas un pielikumu. Raksturvārdi: gitija, sporu-putekšņu analīze, aļģes, mikroskopiskās atliekas.
