CLOSEUP #3
description: <p style="text-align: justify;">LOCALITY: Villa Ahumada, Las Lamentos, Chihuahua, Mexico <br /><br />3" across <br /><br />Wulfenite from Las Lamentos, Mexico was a type of staple mineral specimen at American mineral shows during the 1970's. Around 12,000 specimens of wulfenite from Las Lamentos were mined. Almost amazingly, the worldwide mineral market absorbed all of them. This is evidenced by the fact that so few fine quality specimens of wulfenite from Las Lamentos, Mexico are available at modern mineral shows in the United States. <br /><br />Wulfenite is a lead molybdate. It is found in the oxidized zone of lead mines. For wulfenite genesis to occur, galena and molybdenite must be present in the primary ore. In aqueous solution, lead cations and molybdenite anions combine to form colorful wulfenite specimens like this fine wulfenite specimen from Las Lamentos, Chihuahua, Mexico. <br /><br />The San Francisco Mine, Sonora Province, Mexico is another prolific wulfenite producing locality. Several mines in Arizona also produce fine wulfenite specimens. Of course, the most famous Arizona wulfenite locality is The Red Cloud Mine. <br />  <br />This piece was traded from Kevin Ward after I viewed it on his website in 2014.   <br />  <br />Photo by Matthew Webb of Melbourne, Victoria, Australia </p>
