Abstract

fetched live from OpenAlex

Islands play an important role in marine economic development,oceanic right ascription,and national defense.So,the study of the origin classification of islands is of not only theoretic significance,but is of also important applied value.Traditionally,islands are divided into continental island,oceanic island(volcanic island,coral island) and alluvial island in the ocean.This kind of classification can no longer adapt to match the new progress in the Earth Science today.According to plate tectonic theory and oceanic landforms system,the paper explains the origin of islands,and a new classification system of ocean island is proposed.We divide islands into geotectonic-geomorphic system island(continental terrace island,island of island arc,island of oceanic basin,mid-oceanic ridge island)and exoenetic force-geomorphic system island(sand island,coral island).At the same time,traditional classification is revised,and islands are divided into continental island,oceanic island(volcanic island and coral island),sand island and tectonic melange complex island.ClassificationTectonic or depositionType of islands(example)EndogenicsystemContinental terraceCoastal continental island(Newfoundland Is.)Swell symon continental I.(Taiwan Is.)Continental volcanic I.(Weizhou Is.)Island arc edgeoceanic basinIsland arc continental island(Sumatera Is.)Island arc volcanic island(Kraktau volcano Is.)Subducting accretion island(Mentawai Is.Andaman Is.)Ocean basin micro continental blockAseismic ridges volcanic island(Hawaii Is.Line Is.)Microplate islands(Greenland Is.)Oceanic volcanic island(Loyalty Is.)Mid-oceanic ridgeMid-oceanic ridge volcanic island(Iceland Is.Easter Is.)Structure fault island(Revillagigedo Is.)Exogenetic force-geomorphic system islandMud-sand depositionEstuary sand island(Chongming Is.)barrer island(Caofeidian Is.)erosion sand island(Dongsha Is.)Biology depositionCoral island(Maldives Is.)

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
