ABSTRACT: Autogenic controls have significant influence on deep-water fans and depositional lobes morphology. In this work, we aim to investigate autogenic controls on the topography and geometry of deep-water fans. The influence of the sediment concentration of turbidity currents on deep-water fans morphology was also investigated. From the repeatability of 3D physical modeling of turbidity currents, two series of ten experiments were made, one of high-density turbidity currents (HDTC) and another of low-density turbidity currents (LDTC). All other input parameters (discharge, sediment volumetric concentration and grain size median) were kept constant. Each deposit was analyzed from qualitative and quantitative approaches and statistical analysis. In each experimental series, the variability of the morphological parameters (length, width, L/W ratio, centroid, area, topography) of the simulated deep-water fans was observed. Depositional evolution of the HDTC fans was more complex, showing four evolutionary steps and characterized by the self-channelizing of the turbidity current, while LDTC fans neither present self-channelizing, nor evolutionary steps. High disparities on the geometrical parameters of the fans, as characterized by the elevated relative standard deviation, suggest that autogenic controls induced a stochastic morphological behaviour on the simulated fans of the two experimental series.

The new family Belomitridae is established for the deep-water buccinoid genus Belomitra P. Fischer, 1883, based onmorphological (shell and radulae) and molecular evidence. The rachiglossate radula is uniquely characterized by amulticuspid rachidian and lateral teeth with very long narrow bases and two small cusps closer to tip. Molecular anal-ysis of a reduced set of Buccinoidea did not resolve the group as a clade, but shows that Belomitridae forms a wellsupported clade within Buccinoidea. Species of Belomitra have adult sizes in the 7–53 mm range; they live in deepwater, mostly in the 500–2,000 meters range, at low and mid latitudes. Eleven valid species described from the Indo-Pacific were originally named in the families Buccinidae, Columbellidae, Cancellariidae, Volutidae, and Turridae.Fourteen new species are described: Belomitra nesiotica n. sp. (Society Islands to Tonga and Fiji in 580–830 m), B.bouteti n. sp. (Society and Tuamotu Islands in 430–830 m), B. subula n. sp. (Solomon Islands to Vanuatu in 760–1110m), B. caudata n. sp. (Sulu Sea in 2300 m), B. gymnobela n. sp. (South Pacific, eastern Indonesia and Philippines in780–2040 m), B. hypsomitra n. sp. (Fiji in 392–407 m), B. brachymitra n. sp. (Fiji in 395–540 m), B. comitas n. sp.(Madagascar and Philippines in 1075–1110 m), B. minutula (Coral Sea in 490 m), B. granulata n. sp. (New Caledoniain 105–860 m), B. reticulata n. sp. (Tonga and Fiji to New Caledonia in 395–656 m), B. decapitata n. sp. (IndianOcean and New Caledonia in 3680–4400 m), B. admete n. sp. (off Sri Lanka in 2540 m), and B. radula n. sp. (Madagascar in 367–488 m).Key-words: Buccinoidea, molecular phylogeny, morphology, anatomy, radula, deep-water fauna
