alkaline earth metals
alcalinotérreos
El nombre de alcalinotérreos proviene del nombre que recibían sus óxidos, tierras, que tienen propiedades básicas (alcalinas).
The alkaline earth metals are the series of elements in Group 2 (IUPAC style) of the periodic table: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra) (though radium is not always considered an alkaline earth due to its radioactivity).
The alkaline earth metals are named after their oxides, the alkaline earths, whose old-fashioned names were beryllia, magnesia, lime, strontia and baryta. These were named alkaline earths because of their intermediate nature between the alkalis (oxides of the alkali metals) and the rare earths (oxides of rare earth metals). The classification of some apparently inert substances as 'earths' is millennia old. The earliest known system used by the ancient Greeks consisted of four elements, including earth. This system was later refined by philosophers and alchemists such as Aristotle (4th century BC), Paracelsus (first half of 16th century), John Becher (mid 17th century) and Georg Stahl (late 17th century), with later thinkers subdividing 'earth' into three or more types. The realization that 'earths' were not elements but compounds is attributed to the chemist Antoine Lavoisier. In his Traité Élémentaire de Chimie (Elements of Chemistry) of 1789 he called them Substances simples salifiables terreuses, or salt-forming earth elements. Later, he suggested that the alkaline earths might be metal oxides, but admitted that this was mere conjecture. In 1808, acting on Lavoisier's idea, Humphry Davy became the first to obtain samples of the metals by electrolysis of their molten earths.

: The presence of alkaline earth metals under these circumstances is chemically impossible! The asker has mentioned that there are many mistakes in the source text.

Spanish term (edited):
alcalinotérreos
alkaline earth metal oxides
As the metals themselves are not found naturally and are not likely to be produced under biological conditions, and as the context given refers to carbonates, minerals and silica, this is my suggestion derived from the original definition of "alkaline earths", i.e. the minerals beryllia, magnesia, lime, strontia and baryta, which are the oxides of Be, Mg, Ca, Sr and Ba, respectively.

In ash, they are most probably oxides or carbonates. As the source document lists the elements without specifying the exact compounds, I think it is reasonable to write "...mostly carbonates and alkaline earth metals, as well as silicon."
NB.: NOT "alkaline earth metal carbonates"

The author just stated that the ash contains "[elements] A, B, C, ... and Z", without elaborating on the exact compounds they are forming, probably because this is not relevant to the subject; i.e., the filter's biological characteristics (I presume). He just stated that "[elements] A, B, C, ... and Z are present".
"Carbonatos" is most probably an indirect alusion to the ash's carbon content.

Dr. Andrew Frankland
: That would make it alkaline EARTH metals. Many people, even some chemists, fail to distinguish between the alkali metals (group 1) and the alkaline earth metals (group 2).
