The Marmato mine is an underground gold and silver mine at Marmato in Colombia's Caldas Department, wholly owned by Canada's Aris Mining and mined since pre-Colombian times.
Maroon
Maroon is a dark brownish red, standardized on the web as the CSS named color maroon, hexadecimal #800000, or rgb(128, 0, 0), meaning half-intensity red.
Mars

Mars Exploration Program
The Mars Exploration Program is NASA's long-term robotic program to study Mars, created after the 1993 loss of Mars Observer, with rovers and orbiters pursuing life, climate, and geology goals.
Mars–van Krevelen mechanism in N2 reduction on nitrides
The Mars–van Krevelen mechanism in nitrogen reduction is a catalytic pathway in which lattice nitrogen of a metal nitride is released as ammonia and replenished by gaseous N2.
Marsh gas
Marsh gas, also called bog gas, is the methane-rich gas produced by bacterial decomposition of organic matter underwater in marshes and swamps; wetlands are its largest natural source.
Marsha Berger

Marshall Rosenbluth (1927–2003) was an American plasma physicist and fusion researcher, called "the dean of plasma physics," who derived the Rosenbluth formula and won the National Medal of Science.
Marshall-Palmer drop size distribution
The Marshall-Palmer drop size distribution is an exponential model of how many raindrops of each size are present in rain, proposed at McGill University in 1948.
Marsquake
A marsquake is a seismic event on Mars, caused by faulting, meteorite impacts, or thermal stress, first unambiguously recorded by NASA's InSight lander in 2019.
Marston Morse
Marston Morse (1892–1977) was an American mathematician who created Morse theory, linking a function's critical points to a space's topology, and spent much of his career at Princeton's Institute for Advanced Study.
