[ES] Se da cuenta de las actividades realizadas durante la segunda reunión de la Comisión internacional para la petrología del carbón, celebrada en Lieja, del 23 al 25 de mayo de este año, resumiendo brevemente en primer lugar, las comunicaciones que los petrólogos de diferentes naciones presentaron sobre temas concernientes a instrumentos, métodos y resultados de observación y análisis, petrología teórica, y problemas relacionados con la petrología aplicada y con la geología. A continuación se exponen los principales resultados de los trabajos sobre el léxico petrográfico, indicando el estado en que se encuentra actualmente la nomenclatura internacional de los componentes del carbón (macerales y microlitotipos), y se transcriben las principales observaciones y proposiciones emitidas por la delegación española,.especialmente la que se refiere a la nueva distribución de los microlitotipos, en particular de los grados intermedios (Zwischenstufen) vitrita-durita.
[EN] An account is given about the activities carried out during the Second Meeting of the International Committee for Coal Petrology, which took place in Liege from May 23rd. to 25th. of this year. Firstly, the communications presented by petrologists of different countries about matters concerned to instruments, methods and results reached through microscopical observation and analysis, theoretical petrology and some problems related to applied petrology and geology, are briefly summarized. Afterwords, the main resuhs got on the line of petrographic lexicon are shown, pointing out the present stage overcome by international vocabulary on coal components (macerals and microlithotypes). At last, the principal observations and propositions suggested by the Spanish delegation are transcribed, specially those related to a new distribution of microlithotypes and, particularly, the intermediate stages (Zwischenstufen) vitrite-durite.
