Madini mapya yagunduliwa Mererani, Tanzania

Madini mapya yamegunduliwa nchini Tanzania, katika eneo lenye madini ya kipekee la Manyara, na kupewa jina Merelaniite.

Jina hilo limetokana na eneo ambalo madini hayo yalipatikana, Merelani (Mererani) katika milima ya Lelatema katika wilaya ya Simanjiro katika eneo la Manyara.

Eneo hilo linafahamika sana kwa madini ya Tanzanite.

Madini hayo yaligunduliwa na wataalamu kutoka Chuo Kikuu cha Kiteknolojia cha Michigan cha Marekani, makavazi ya historia asilia ya London, chuo kikuu cha Di Firenze cha Italia na makavazi ya historia asilia ya Smithsonian ya Washington.

Wataalamu sita waliofanya uchunguzi, kwenye makala iliyochapishwa kwenye jarida la Minerals (Madini) wanasema madini hayo yana vipande vinavyofanana na sharubu vya rangi ya kijivu vya urefu wa milimita moja hivi, ingawa kuna baadhi vyenye urefu wa hadi mililita 12.

Kipenyo cha vipande hivyo ni mikrometa kadha.

Madini hayo yanakaribiana na madini ya zoisite (aina ya tanzanite), prehnite, stilbite, chabazite, tremolite, diopside, quartz, calcite, graphite, alabandite na wurtzite.

Tanzania kuwaruzuku wachimbaji wadogo wa madini

Serikali kupitia Wizara ya Nishati na Madini imepanga kuwapatia ruzuku wachimbaji wadogo wa madini ili kuongeza mchango wa madini katika pato la taifa kutoka asilimia 3.5 ya sasa hadi 10.

Waziri wa Nishati na Madini, Profesa Sospeter Muhongo alisema kuwa “Sekta ya Madini inachangia asilimia 3.5 ya pato la Taifa,lakini dhamira yetu ni kwamba wakati tunaingia kuwa nchi ya kipato cha kati madini yanapaswa kuchangia si chini ya asilimia kumi”

Aidha aliongeza kuwa dhamira ya Serikali ni kuhakikisha Tanzania inakuwa nchi ya viwanda ifikapo 2025, hivyo adhma ya Wizara yake ni kuongeza kasi ya pato linalotokana na sekta ya madini na

Aliongeza kuwa ili mafanikio hayo yafikiwe Serikali imekusudia kupandisha hadhi ya wachimbaji wadogo ili wafikie ngazi ya kuwa wachimbaji wa kati na hivyo sekta hii itachangia pato la Taifa kwa kiasi kikubwa.

Aidha Waziri Muhongo alisema kuwa Serikali imepokea pesa mkopo wa Tsh. Bilioni 3 kutoka Benki ya Dunia na imepanga kutoa ruzuku ya vifaa kwa wachimbaji hao wakati wowote kuanzia sasa.”Serikali imeshaanza kutoa maeneo na kufikia tarehe 15 septemba tutaanza kutoa ruzuku kwa wachimbaji hao” alisema Prof. Muhongo.

Akizungumzia hatua zilizochukuliwa na Serikali katika kuzuia utoroshaji wa madini nje ya nchi Profesa Muhongo alisema kuwa tangu mwaka 2012 Wizara yake iliweka madawati ya ukaguzi wa madini katika viwanja vya ndege vya Mwalimu Nyerere Jijini Dar es Salaam,Kilimanjaro na Mwanza na wakafanikiwa kukamata madini zaidi ya tani kumi.

“Madini haya mapya yametambuliwa na taasisi inayoyapa majina madini, IMA CNMNC (2016-042), na kupewa jina linalotokana na eneo yalipogunduliwa kwa heshima ya wachimba migodi wa eneo hilo wa zamani, wanaoishi na wanaofanya kazi,” makala ya wataalamu hayo inasema.

“Wilaya ya Merelani imekuwa maarufu tangu mwishoni mwa miaka ya 1960 kutokana na aina ya madini ya thamani ya rangi ya samawati kwa jina zoisite yafahamikayo kama tanzanite, lakini ni eneo muhimu sana kwa wanaotafuta madini ya kipekee na ni eneo la kusisimua sana kutafuta madini mapya,” John Jaszczak, mwanafizikia katika Chuo Kikuu cha Kiteknolojia cha Michigan, na aliyeongoza katika kuandika makala kuhusu ugunduzi wa madini hayo anasema.

Madini hayo yalitambuliwa mara ya kwanza mwaka 2012 na Simon Harrison na Michael Wise, bila wataalamu hao kuyafahamu vyema, pale walipogundua vitu vilivyoonekana kama nyaya ndogo zilizokuwa zimedunga na kuingia ndani ya vipande vya madini ya chabazite.

Baadaye uchunguzi zaidi ulifanywa na ikagunduliwa kwamba yalikuwa madini tofauti.
