Cordierite is a very rare mineral in the conditions of the Most Basin, and its presence has so far always been associated with thermal metamorphism. The first mention of cordierite, as a product of clay transformation in porcelainites, dates back to the 1980s (Fediuk, 1988), but no macroscopically visible specimen has been found so far. The first such specimen is a blue-gray bulk sample measuring approximately 5 x 5 cm, which was found in 2016 at the ČSA quarry (Řehoř, 2016). The main attention is now focused on a new discovery of massive cordierite in 2024.
The issue of determining the emission factor of methane from brown coal

On July 15, 2024, the European Parliament and Council Regulation EU 2024/1787 on the reduction of methane emissions in the energy sector was issued. This regulation, among other things, addresses the determination of the emission factor for brown coal mined in open-pit mines in the Czech Republic. The emission factor is expressed as the amount of methane released per unit of coal weight, usually given in kilograms per ton, or sometimes in grams or liters per ton. Currently, there is no legislative or normative standard procedure for determining methane emissions, and various methods using existing technologies can therefore be applied.

On November 5-6, 2024, the International Workshop on Best Practices in Coal Mine Methane Monitoring, Capture, and Use was held in Katowice, Poland, where available technologies and strategies for monitoring, capturing, and using methane from coal mines (CMM - Coal Mine Methane) were presented. The congress was organized by the United Nations Economic Commission for Europe (UNECE) in cooperation with ICE-CMM Poland, which is the International Centre of Excellence focusing on methane emissions from coal mines.

VUHU is part of an international team that has been working on the important European reclamation project REECOL since 2023. The article briefly summarizes the successful completion of the WP3 initial research package, which was led by VUHU. The main attention is paid to the launch of the WP5 research package, which is focused on short-term and long-term monitoring of case study areas soil parameters. These are briefly characterized in the paper and the monitoring methodology is described in detail. In conclusion, the identified input pedological parameters of the case areas are presented and evaluated.
