(2002) and {B}aratoux and {M}elosh (2003) require further evaluation. {N}ew observations, experiments, or theoretical considerations presented in this special issue promise an important step forward, based on a renewed effort to resolve the enigmatic origin of these important features.}, keywords = {{MONDE}}, booktitle = {{S}hatter cones : nature and genesis}, journal = {{M}eteoritics and {P}lanetary {S}cience}, volume = {51}, numero = {8 ({N}o sp{\'e}cial)}, pages = {1389--1434}, ISSN = {1086-9379}, year = {2016}, DOI = {10.1111/maps.12678}, URL = {https://www.documentation.ird.fr/hor/fdi:010068667}, }
