Como si fueras un detective de la ciencia forense, con solo una gota de un &#8220;l\u00edquido m\u00e1gico&#8221;, puedes desvelar la espectacular historia de esa roca: el lugar donde naci\u00f3 hace decenas de millones de a\u00f1os.<\/p>\n<p>Hoy nos adentraremos en el misterio de dos rocas que parecen gemelas: la caliza (sekkaigan) y el chert (chart).<\/p>\n<h3>Los sospechosos: Dos rocas id\u00e9nticas<\/h3>\n<p>Aqu\u00ed tenemos dos rocas que se parecen much\u00edsimo. Una es un regalo dejado por las criaturas del oc\u00e9ano prehist\u00f3rico, y la otra es una roca dura formada por la solidificaci\u00f3n de los esqueletos sil\u00edceos de plancton. \u00bfCu\u00e1l es cu\u00e1l? La clave para resolver este enigma est\u00e1 escondida en la diferencia de &#8220;composici\u00f3n&#8221; de cada roca.<\/p>\n<p>Caliza: Se form\u00f3 por la acumulaci\u00f3n de restos de organismos marinos antiguos, como corales, conchas y esqueletos de plancton, en el fondo del mar. Su componente principal es el carbonato de calcio (CaCO3). La tiza que se usa en las escuelas y las l\u00edneas blancas de los campos deportivos tambi\u00e9n son de esta familia.<\/p>\n<p>Chert: Es una roca que se form\u00f3 lentamente en las profundidades marinas a lo largo de millones de a\u00f1os, a partir de los esqueletos sil\u00edceos de plancton microsc\u00f3pico, como los radiolarios (housanchu). Su componente principal es el di\u00f3xido de silicio (SiO2). Como comparte el mismo componente que el cuarzo, es extremadamente dura.<\/p>\n<p>Si la composici\u00f3n es distinta, \u00a1tiene que haber una prueba definitiva! Es aqu\u00ed donde entra en acci\u00f3n nuestro &#8220;l\u00edquido m\u00e1gico&#8221;: una soluci\u00f3n diluida de \u00e1cido clorh\u00eddrico.<\/p>\n<h3>\u00a1El momento de la verdad!
