RODINIA 750 mil yrs ago

GONDWANALAURENTIA 550 mil yrs ago

PANGEA 245 mil yrs ago

Time: 1 billion ago to today Place: 3 supercontinents colliding, splitting, reuniting

GONDWANALAURENTIA 550 mil yrs ago

GONDWANALAURENTIA 550 mil yrs ago

Melt-water rivers from high- elevation glaciers deposited stones (BOSTON BASIN)

PANGEA 425-245 mil yrs ago

Tectonic rifts & collisions buried 400-1,550 ft. stone deposits—deeply—as land masses migrated north.

Cemented into a conglomerate

Heat & pressure cemented these stone deposits

(Called “ROXBURY CONGLOMERATE”)

Pressure created fractures in the conglomerate (through individual stones!!!), which later filled with liquefied quartz

Quartz vein intrusion in conglomerate

550 mil yrs ago

GONDWANA

LAURENTIA

PANGEA 245 mil yrs ago

1.  Broken off GONDWANA (about 550 mil yrs ago)

2. Collided with each other in process 3. Welded to LAURENTIA (about 370 mil yrs ago) 4. Been sandwiched into PANGEA (about 245 mil yrs ago)

Then, about 200 mil yrs ago, began to rift apart to create modern continents. (Rifting continues)

Why are we giving

you a Lucky Stone?

Lucky Stones, ancient and enduring, serve as touchstones, reminding us of our collective commitments to our shared goals on

Touchstones ~ Lucky Stones

behalf of all children at-risk for reading difficulties.

Like the Lucky Stone, our commitments must endure

over time & persist in all kinds of environments …

… which generate forces and conditions that challenge, shape, sometimes even enhance, our efforts.

Like the Lucky Stone, our individual attributes are remarkable

… but these can intensify when brought together.

To succeed, we must endure but change, stand alone but work collectively.

We also need a bit of luck, which the lucky stone brings to you …
